What Can We Learn from the Ponds in the Ruby Mountains?
The Ruby Mountains rise between Ruby Valley to the east and Lamoille and Huntington valleys to the west. They stretch for 98 km (61 miles) from Secret Creek in the north to Overland Pass in the south. They are up to 21 km (13 miles) wide south of Lamoille Canyon and narrower elsewhere.
The highest peaks in the Ruby Mountains are on a sharp east-west ridge south of Lamoille Canyon. They include Ruby Dome at 3,471 m (11,387′), Mount Fitzgerald (3,418 m, 11,215′), and Snow Lake Peak (3,396 m, 11,137′). Most other high peaks are along the central crest of the range. Soldier Peak, near the north end, has an elevation of 3,075 m (10,089′); King Peak, near the middle, is at 3,362 m (11,031′); and Pearl Peak, in the south, reaches 3,306 m (10,847′). The 2,000 m (6,560′) contour encloses pretty much all of the mountainous and hilly terrain. The east side of the range is, overall, steeper than the west side but the west side has long canyons with steep walls.
The vegetation of the Ruby Mountains seems to be unique to me. It differs from what I have seen in other high ranges of the Great Basin, such as the Jarbidge Mountains and Toiyabe Range. The paucity of trees and abundance of brush north of Harrison Pass suggests the Ruby Mountains have been burned repeatedly over the last century or two. Lower slopes south of Harrison Pass may have pinyon pine but I didn’t see any along the Ruby Crest Trail. Limber or white pine is scattered along the ridges or present in groves on the moister slopes. Aspen is surprisingly common at high elevations but not abundant. Instead of trees, dense shrubbery thrives on the relatively abundant moisture of the Ruby Mountains.
The brush in the Ruby Mountains is thick enough to pose a serious impediment to off-trail hiking. Unlike much of Nevada, sagebrush does not dominate the Ruby Mountains except on higher, rockier slopes. Paradoxically, it generally offers the easiest hiking. Also unlike much of Nevada, antelope bitterbrush and mahogany seem to be uncommon, at least along the Ruby Crest Trail. What dominates are dense masses of the intricately branched, manzanita-like snowbrush that often have slope-parallel branches which prevent boot contact with the ground. Walking on, rather than through, the brush results in stability and breakthrough problems. Thickets of contorted aspen less than 2 m (6 1/2′) high are just as bad. Streams and wet meadows have willows that, like snowbrush, form impenetrable, intricately branched masses that can grow up to 2 m (6 1/2′) high. Getting to the edge of a pond to look for fairy shrimp can be a problem. Be forewarned.
The redeeming feature of the vegetation in the Ruby Mountains is the wildflowers. They are diverse and locally abundant.
Almost all of the Ruby Mountains are within the boundaries of the Humboldt-Toiyabe National Forest. However, the northern part of the range is within the railroad checkerboard where sections of public land alternate with sections of private land. There are also areas where the public lands are separated from the Forest boundary by private land. This begs the question of why the boundary was placed within private land rather than at the edge of the public land. Otherwise, the inholdings of private land are minor. The largest are on the west side of the southern Ruby Mountains on Lindsay Creek, South Cass House Creek, Mitchell Creek, Sherman Creek, Sestanovich Creek, and Willow Creek. Close to half of the Ruby Mountains north of Harrison Pass lie within the Ruby Mountains Wilderness, which has a shape that is too bizarre to describe but may be a good illustration of the political process that created it.
Public access to the Ruby Mountains is limited because few public roads reach the Forest boundary. The 2 exceptions are the paved road in Lamoille Canyon and the partly paved road over Harrison Pass. Elsewhere, roads into the National Forest cross private land. In a few cases, such as to the “Overland Lake” trailhead, the Forest Service has an agreement with the land owner to allow public access. In other cases, it doesn’t. Consequently, the lower ends of many trails up the valleys of the Ruby Mountains are not accessible without specific landowner permission. That leaves the Ruby Crest Trail from Lamoille Canyon to Harrison Pass as the principal means of public access. Be aware that the southern trailhead of the Ruby Crest Trail is 2.8 miles north of Harrison Pass and can be reached only by high-clearance, 4-wheel drive vehicles. It is a very poor, locally steep, one lane road. Harrison Pass is at about 2,200 m (7,220′). The Lamoille Canyon end of the Ruby Crest Trail starts at pavement at about 2,700 m (8,860′).
Glaciers in the Ruby Mountains
Glaciers have carved long u-shaped canyons on the west side of the Ruby Mountains. The biggest, most accessible, and most scenic is Lamoille Canyon. The flatter floors of these valleys are more favorable for ponds than the usual v-shaped canyons. At the heads of some canyons, short cirques from the most recent glacial advances have ponds. Examples include ponds at the upper ends of Middle Fork Smith Creek and South Fork Smith Creek canyons. Hanging valleys also offer platforms for ponds. Those on the west side of upper Long Canyon do not have ponds on the 7.5-minute topographic quadrangle but “Lost Lake” is in a hanging valley off Rattlesnake Creek canyon. Such glacial features have increased the abundance of possible fairy shrimp habitats.
The east side of the Ruby Mountains was apparently too steep during the glacial periods for glaciers to do much good for ponds. The glaciers may have just plunged to the valley floor without forming substantial platforms where ponds could form. One exception is “Overland Lake”.
Fish-stocking in the Ruby Mountains
Although the Ruby Mountains don’t have any large lakes, almost all of those it does have have been stocked with fish. The web site rubymountains.net has a table of unknown vintage that lists 25 lakes and indicates 6 do not have fish (counting the 2 “Dollar Lakes” as 1 and including lakes in the nearby East Humboldt Range). However, a May 27, 2022 article in the Elko Daily Free Press by Joe Doucette (“Alpine fishing in Nevada: The lowdown on high mountain lakes”) indicates that “Seitz Lake” is now periodically stocked by Nevada Department of Wildlife. According to the rubymountains.net table, the smallest lake with fish, “Cold #2”, has an area of 1.8 acres (0.7 hectare). The largest lake is the 29-acre (12 hectare) “Echo Lake”.
As in the East-Central Sierra Nevada, Wind River Mountains, and Snowy Range, fish stocking in the Ruby Mountains could have extirpated numerous fairy shrimp, and other invertebrate, populations. Did any populations survive?

Watchful Beaver Pond is at the upper end of Middle Fork Smith Creek canyon 50 km (31 miles) southeast of Elko. On the 7.5-minute topographic quadrangle, Watchful Beaver Pond is a round pond about 150 m (490′) across. As I was scanning the water and trying to identify the aquatic animals, a beaver paddled by in the distance and watched me. The pond does not have a beaver-constructed dam or lodge; it just has a watchful beaver. There are plenty of willows for it to eat. Watchful Beaver Pond is not in the table of lakes at rubymountains.net.
Watchful Beaver Pond is reached via the Ruby Crest Trail. The trail crosses Middle Fork Smith Creek about 15.5 km (9.6 miles) from the Harrison Pass trailhead. A short distance north of the ford, there is a sign for Middle Fork trail. Although the 7.5-minute topographic quadrangle does not show a Middle Fork trail, The National Map does. The Middle Fork trail has essentially disappeared. However, if you follow what looks like the easiest route up the valley, you will sometimes find yourself on what appears to be a trail. This could be the remains of a human-used trail or a game trail. The same situation occurs in South Fork Smith Creek valley where no human trail is mapped. In any case, hiking up the valley is not bad since the valley floor lacks snowbrush and young aspen thickets.
Elevation: 2,896 m (9,501′)
July 14, 2022
Although there was not much of a trail, the hike was not difficult. The greatest annoyance was socks packed full of pointy grass seeds that took more than 10 minutes to remove. I had enough time to hike up to the pond from the Ruby Crest Trail and back and to complete the 9.2 km (5.7 miles) hike from South Fork Smith Creek to “Overland Lake” in one day.
- 120 m x 150 m; more than 100 cm deep and could be 200 cm deep.
- Water is clear; 22 C at 1130.
- No fairy shrimp.
- Abundant caddisfly larvae (Trichoptera), black beetles less than 10 mm long, gray-brown beetles about 15 mm long, water boatmen (sub-order Heteroptera, family Corixidae), rare 1-2 mm copepods, snails, beaver.

“Overland Lake” Upper Pond is 48.5 km (30.0 miles) southeast of Elko. It is about 70 m (230′) higher and 250 m (820′) southwest of “Overland Lake”. On the 7.5-minute topographic quadrangle, “Overland Lake” Upper Pond is about 150 m (490′) across. “Overland Lake” Upper Pond is not in the table of lakes at rubymountains.net. The outlet of “Overland Lake” Upper Pond disappears into boulders on a steep slope above “Overland Lake” so the pond is not accessible to fish in “Overland Lake” under natural conditions.
Being next to “Overland Lake”, “Overland Lake” Upper Pond is along the Ruby Crest Trail. “Overland Lake” is approximately 22.5 km (14.0 miles) from the trailhead north of Harrison Pass and considerably farther from Lamoille Canyon. “Overland Lake” can also be reached by a very steep hike from the trailhead off the Ruby Valley road. Because it is one of the most accessible lakes in the Ruby Mountains and has fish, “Overland Lake” probably has at least one camping party every night during the summer. A few moderately separated camping sites are available at the lake.
Elevation: 2,959 m (9,710′)
July 14, 2022
The pond is significantly higher than “Overland Lake” and clearly not accessible to fish in “Overland Lake”.
- 60 m x 100 m; probably more than 100 cm deep.
- Clear water; 20 C at 1730.
- No fairy shrimp.
- Fish guts.
“Overland Lake” Upper Pond is not an effortless climb from “Overland Lake” so no one would carry a fish up here to gut it. That’s basically all the organic matter I saw in the pond. I didn’t see any invertebrates at all, which is typical of ponds with fish.

“North Furlong Lake” is 42.5 km (26.5 miles) southeast of Elko. It is 250 m (820′) long and 120 m (390′) wide on the 7.5-minute topographic quadrangle. In spite of its small size, it is labeled on the 1:100,000-scale BLM map. The lake is not connected to North Furlong Creek. The table at rubymountains.net indicates “North Furlong Lake” does not have fish.
“North Furlong Lake” is a short distance off the Ruby Crest Trail about 43.5 km (27.0 miles) from the Harrison Pass trailhead and probably half that distance from the Lamoille Canyon trailhead. There is a sign on the Ruby Crest Trail for the North Furlong Creek trail, which leads close to “North Furlong Lake”. The lake is a little more than 1 km (0.6 miles) away across easy terrain. The trail shown on the 7.5-minute quadrangle does not approach the lake while that on The National Map does. The trail depicted on The National Map better represents the most obvious trail today. The North Furlong Creek Trail goes all the way down the canyon but there is no public access to the lower end.
Elevation: 2,925 m (9,600′)
July 15, 2022
The broad area of flat ground to the north and west of “North Furlong Lake” seems to be covered by ground moraine of mixed mud and gravel. The lake is in an odd depression all by itself with no active outlet. Lots of mosquitoes.
- 100 m x 250 m; probably more than 100 cm deep.
- Clear water; 20 C at 1730.
- No fairy shrimp.
- Caddisfly larvae (Trichoptera), greenish-brown beetles less than 10 mm long scurrying around on the pond bottom, fast swimmers with multi-segmented bodies lacking distinct thoraxes and abdomens may be amphipods, abundant dark brown copepods 2+ mm long, snails.
“North Furlong Lake”, looking east (extreme wide-angle view). There are small shoreline terraces on the slope on the left (north) side of the lake that mark the declines in water level after it fell below the spill point. They are not visible in the photograph. The lake is now stagnant with no outlet. I don’t know if the terraces formed annually or over longer intervals but there are a dozen or more of them. They could reflect recent drought or longer term changes in precipitation.
View of “North Furlong Lake” to the northwest on the way down from Log Jam Pond. North Furlong Creek is in the small groove with scattered trees in the middle distance. The bathtub ring around the lake indicative of declining water levels is quite apparent. Before the lake level dropped so low, the outlet would have been off the lower left edge of the photograph. How long has the lake been drying up?
Possible amphipod in “North Furlong Lake”. The greenish-gray blur (slow shutter speed) at center is a little less than 10 mm long and has a segmented, rather flat body. There is no distinct head or abdomen and the body tapers slightly toward both ends. It is a fast swimmer. What else could it be?
Beetle in “North Furlong Lake”. This is one of the beetles that mostly scurry around on the bottom of the lake.
Abundant dark brown copepods at the edge of “North Furlong Lake”. I don’t think I have ever seen copepods this big. They are 2 mm or more long. They are fatter at the front and, so, unlikely to be cladocerans.
Willows and Rocks Pond (Ruby Mountains Ranger District, Humboldt-Toiyabe National Forest; Ruby Mountains Wilderness)
Willows and Rocks Pond is 250 m (820′) southwest of “North Furlong Lake” in a small meadow at the base of a cliff. Angular rocks on the west side of the pond are likely from a rock fall. The meadow is nearly filled with willows and difficult to cross. On the 7.5-minute quadrangle, Willows and Rocks Pond is less than 30 m (100′) across. I didn’t see a 2nd pond as shown on the map to the west of this pond.
For access, see “North Furlong Lake”.
Elevation: 2,913 m (9,560′)
July 15, 2022
Getting through the willows to reach the pond is a challenge but at least the rocks on the south shore provide some open space. Mosquitoes are bad.
- 20 m x 30 m; probably less than 100 cm deep.
- Water clear; 21 C at 1800.
- No fairy shrimp.
- Black beetle 12 mm long, rare amphipods(?) like those in “North Furlong Lake”, caddisfly larvae (Trichoptera), abundant copepods less than 1 mm long.

Toe of Talus Pond (Ruby Mountains Ranger District, Humboldt-Toiyabe National Forest; Ruby Mountains Wilderness)
Toe of Talus Pond is 350 m (1,150′) south of “North Furlong Lake”. It is at the end of a pile of angular boulders forming talus at the base of the cliff to the southwest. Toe of Talus Pond is less than 30 m (100′) across on the 7.5-minute quadrangle.
For access, see “North Furlong Lake”. Rather than fight the willows, I hiked across the rocks at the southwest edge of the little valley from Willows and Rocks Pond to this pond.
Elevation: 2,961 m (9,715′)
July 15, 2022
The vegetation is so lush there must be a stream under the rocks and willows in the little valley with Willows and Rocks Pond and Toe of Talus Pond. Because of the willows, there are only a couple of spots where I can get to the water. Consequently, my observations can’t be considered comprehensive. More annoying mosquitoes. Thank goodness the repellent is working.
- 25 m x 40 m; doesn’t look deeper than 100 cm.
- Clear water; 20 C at 1830 (same as air temperature).
- No fairy shrimp.
- Dragonfly(?) larvae 15 mm long that are narrow at the front and fatter toward the rear and don’t swim much with their short legs, water boatmen (sub-order Heteroptera, family Corixidae), or possibly backswimmers (sub-order Heteroptera, family Notonectidae).
Toe of Talus Pond, looking north from a talus boulder. “North Furlong Lake” is out of sight below the lip on the far side of the pond. That is possibly Mount Fitzgerald above the low spot in the ridge on the far side of North Furlong Creek.
Log Jam Pond (Ruby Mountains Ranger District, Humboldt-Toiyabe National Forest; Ruby Mountains Wilderness)
Log Jam Pond is 400 m (1,310′) southeast of “North Furlong Lake” on a bit of a ledge about 75 m (250′) higher than the lake. The 7.5-minute quadrangle shows the pond as slightly larger than Willow and Rocks Pond and Toe of Talus Pond but still less than 50 m (165′) across. There are numerous logs in the water.
For access, see “North Furlong Lake”. Climbing through the limber pine directly from “North Furlong Lake” would be steeper but easier than following a more gentle, willow-clogged route past Toe of Talus Pond, unless you are coming from Toe of Talus Pond.
Elevation: 2,996 m (9,830′)
July 15, 2022
Was there an avalanche that dropped all these logs in the pond? No clues on the slope above, which has several standing limber pines. Willows are still a problem as I can only get to the water in a couple of places. I can’t walk on the logs because they are floating, as my wet boot proves. Fading light makes it hard to see what’s in the water. At least the thunderstorms have dissipated after a threatening day.
- 50 m x 70 m; depth greater than 100 cm.
- Water clear; 20 C at 1900.
- No fairy shrimp.
- Black beetles; black, oval, 2 mm long, fast swimmers that stay close to bottom and look like ostracods but I saw one come to surface for air, which ostracods don’t do; sparse 2+ mm copepods, snails.
Log Jam Pond, wide-angle view looking south along shoreline with logs. Willows are thick all the way around the pond. Cliff at left rises to Wines Peak.
Above the Trail Pond (Ruby Mountains Ranger District, Humboldt-Toiyabe National Forest; Ruby Mountains Wilderness)
“Overland Lake” Upper Pond map
Above the Trail Pond is 550 m (1,800′) north of “Overland Lake”. The pond is only 100 m (330′) or so southwest of the Ruby Crest Trail north of “Overland Lake” and about 30 m (100′) above it but it cannot be seen from the trail. Above the Trail Pond is a mere speck less than 25 m (80′) across on the 7.5-minute topographic quadrangle.
For access, see “Overland Lake” Upper Pond. Above the Trail Pond is about 100 m (330′) below “Overland Lake” and can be reached from the northwest end of the lake by scrambling down through the limber pine and across a boulder field. Contrary to The National Map, the Ruby Crest Trail, or at least the one used now, does not go north from “Overland Lake”. At the north end of the lake, it turns east toward the trailhead in Ruby Valley and switchbacks down the hill before branching off and contouring to the northwest below Above the Trail Pond.
Elevation: 2,772 m (9,090′)
July 16, 2022
This is another pond surrounded by aggressive willows and I can reach the water in only a few places.
- 60 m x 80 m; probably somewhat deeper than 100 cm.
- Clear water; 20 C at 1800.
- No fairy shrimp.
- Fish.
The fish I saw were mostly less than 6 cm (2.4″) but one jumped out of the water to grab an insect and made a big splash. It seems unlikely they made it down the hill from “Overland Lake” so this implies people are even stocking ponds this small.
Wide-angle view looking down and to the north at Above the Trail Pond from the edge of a hill north of “Overland Lake”.
Looking south (wide-angle view) across Above the Trail Pond. Water gurgles down the hill from the vicinity of “Overland Lake” through the boulders with willows but the 7.5-minute quadrangle does not show this route as an outlet for the lake. Even if fish made it down through the boulders, there is no stream through the willows into the pond except maybe during periods of very high water. So the fish in Above the Trail Pond were most likely put here by people. The fish are so small I don’t think anyone would bother to try to catch them so what was the point?
Pika Pond (Ruby Mountains Ranger District, Humboldt-Toiyabe National Forest; Ruby Mountains Wilderness)
Pika Pond is 52 km (32 miles) southeast of Elko at the upper end of South Fork Smith Creek canyon. On the 7.5-minute topographic quadrangle, Pika Pond is 100 m (330′) across. Although the area around the pond is rocky, the willows nonetheless encroach on all sides. This makes the most accessible part of the pond the southern shore of angular boulders. Hiking over the rocks and boulders on the way up to the pond, I frequently heard the characteristic squeaks of pikas. Pika Pond is not in the table of lakes at rubymountains.net.
Pika Pond is about a 4 km (2.5 mile) hike from the Ruby Crest Trail crossing of South Fork Smith Creek. That crossing is 13.2 km (8.4 miles) from the trailhead north of Harrison Pass. Maps have no indication of a trail up the canyon to Pika Pond. However, if you backtrack on the Ruby Crest Trail a short distance from the ford, turn off through the mature aspen grove when the trail starts up the hill, and then follow what looks like the easiest route, you will occasionally find yourself on something that looks like a trail. There may well be multiple, little used game trails up the canyon (use both sides of the creek). Unlike the Middle Fork Smith Creek route, the best route up the South Fork Smith Creek passes through several mostly mature aspen groves, generally lacks the grass that leaves your socks filled with prickly seeds, and has several sections of traipsing through leafy flowers. It can be an enjoyable hike.
Elevation: 3,012 m (9,880′)
July 17, 2022
I started up the canyon on the 13th after the hike to the South Fork Smith Creek crossing but I was too tired and it was too late to make it to the pond. The shorter and easier hike from “Overland Lake” today with little food remaining in my pack was a more favorable opportunity. The problem today is the cloudy skies and frequent rumbling. To my surprise and relief, there were only a few sprinkles.
- 150 m x 200 m; depth probably greater than 200 cm.
- Water is clear with green tint; 18 C at 1500.
- No fairy shrimp.
- Black beetles, water boatmen (sub-order Heteroptera, family Corixidae), 10-12 mm long, mayfly nymphs (Ephemeroptera), caddisfly larvae (Trichoptera), abundant 2+ mm copepods.
Wide-angle view of Pika Pond, looking east. Willows are thick along much of the shoreline.

What Can We Learn from the Ponds in the Ruby Mountains?
Glaciation has blessed the Ruby Mountains with more ponds than most mountain ranges in Nevada. The Ruby Mountains have more than 2 dozen lakes and ponds ranging in size up to 30 acres (12 hectares) that are potential fairy shrimp habitat.
All the larger lakes and ponds and some very small ones have been stocked with fish.
None of the 8 ponds I visited have fairy shrimp. 2 have fish in spite of areas less than about 1 hectare (2.5 acres).
The fish-free ponds I visited do have a variety of beetles (observed in 5 ponds), caddisfly larvae (observed in 4 ponds), water boatmen (observed in 3 ponds), and relatively large copepods (observed in 5 ponds). Ponds with fish don’t.
