The Trinity Alps are within the Pacific Coast Rangesphysiographic region, in the Klamath Mountains System, which lies between the California Coast Ranges to the west and the Cascade Range to the east. Elevations range from 1,350 feet (411 m) to 9,001 feet (2,744 m) on Thompson Peak. Other notable peaks include Granite Peak (8,094 feet (2,467 m)) and Ycatapom Peak (7,593 feet (2,314 m)). The Trinity Alps are noted for their scenic views and alpine environment. The range’s alpine flora differs from that found in the Sierra Nevada or the Cascades. Within the Klamath Mountains, adjacent subranges of the Trinity Alps include the Salmon Mountains and Scott Mountains.
The Trinity Alps Wilderness covers 517,000 acres (2,090 km2), making it the second largest wilderness area in California.[2] The area was formerly known as the Salmon-Trinity Alps Primitive Area since 1932 until a series of expansions.
The lowest snowfield in California that does not disappear except in the extreme runs of dry years is located above Mirror Lake at an elevation of 6,600 ft (2,000 m).
The only unambiguous glacier is the Grizzly Glacier, a 15-acre (61,000 m2) icefield on the north side of Thompson Peak, which shows crevasses indicating true motion even on so small an icefield.
Research has shown that some glaciers in the Trinity Alps are more resistant to the effects of global warming than are other California glaciers. According to recent, but incorrect, USGS maps, 35 permanent bodies of snow and several tiny glaciers dot the highest peaks of the Alps.[3]
