Come join the Mount Shasta Trail Association on this strenuous and sometimes steep, 5.5-mile roundtrip hike to the sky scraping granite spires called the Castle Crags. The elevation gain is 2200 feet. We will first walk through the forest to Indian Springs and then hike out in the open, amid the granite slabs and pinnacles where the postcard views of Mt. Shasta and the Crags become more and more spectacular.
Castle Crags are actually part of the Klamath Mountains, not the Cascade Range that lies east and north, and are much older than the Cascades. Castle Crags formed by granitic magma slowly cooling underground (as a “pluton”) and subsequently became exposed at the surface through uplifting and erosion. This is the same way that the granites of Yosemite formed. In fact, the Klamath Mountains broke off from the Sierra Nevada about 60 million years ago. Mount Shasta, in contrast, was formed by relatively recent surface eruptions (within the last several million years), and its rock is andesite.
The event is free and open to the public. Participants should meet at 9 AM Saturday, June 18, 2011, in the fish hatchery parking lot to form carpools. The fish hatchery is located a quarter-mile west of the main Mount Shasta I-5 exit (the middle of the three) on the way to Lake Siskiyou.We will return about 4:30 pm.
