Castle Lake rests in the Great Basin between the Sierra Nevada and the Wasatch Mountains range. The lake can be found in Elko County in northeastern Nevada. Of the largest nearby cities to Castle Lake is Elko, which resides 65 miles northwest. Both Elko and Castle Lake are situated on the eastern edge of the Humboldt Valley of the Ruby Mountain Wilderness. As for other bodies of water, Favre Lake and Liberty Lake can be located to the north. Water outflows from Castle Lake into Kletchner Creek, which also forms a shelf and continues to flow until merging with the South Forks of the Humboldt River to the north northwest.

Geology Around Castle Lake

The formation of the Ruby Mountains occurred when the North American Plate extended. It was once a part of the Basin and Range Province, but faults and flanks on the eastern and western sides separated it. This mountain range is an example of a metamorphic core complex, where the deep crust has been pushed to the surface. As for the Ruby Mountains, lower and middle crust rocks are evident superficially. Moreover, during the most recent ice age, glaciation and erosion carved out distinct features of the Ruby Mountains that can be observed today. Of these features are; cliffs, U-shaped valleys, steep granite mountains, hanging valleys, moraines, glacial gouges, cirques, and tarns. Furthermore, Castle Lake is a glacial tarn that was once carved out by a cirque.

Gold Rush Near Castle Lake

During the mid-19th century, miners that traveled the California Trail thought the mountain range would contain gold. What was discovered were red gemstones speculated to be rubies, giving way to the name of the Ruby Mountains. It was incorrect, however, and the miners had stumbled upon a bounty of garnets.

History Around Castle Lake And The National Forests

Humboldt-Toiyabe National Forest

The Humboldt-Toiyabe National Forest is the second-largest national forest outside of Alaska, but it wasn't always this way. Today's national park is a convergence of many of Nevada's previous national parks. As for the timeline, the oldest, Ruby Mountain National Park, merged with Independence National Forest in 1908 to create the Humboldt National Forest, where Castle Lake resides. Toiyabe National Park has a rocky history. It was founded in 1907 but later concluded to operate after 1932. This was short-lived, as it was merged into the Nevada National Forest in 1938. Another reorganization occurred in 1957 when the land from the Nevada National Forest was split between the Toiyabe National Forest and Humboldt National. Lastly, in 1995 Humboldt and Toiyabe National Forests would merge but still had two unique identities to boot.
