Area Description

This wilderness is named for High Rock Lake located in its northwest corner. The Applegate-Lassen National Historic Trail passes through the northern part of this wilderness. Many of the 1849 emigrants to Oregon and California passed this way, and the scenery remains much the same as it was over a century ago.

The catastrophic event which blocked Box Canyon occurred during the Pleistocene epoch, a time when quiet High Rock Creek, swollen with runoff from the cooler and wetter climate, flowed with the force of a small river. Where did all this water go? Very quickly High Rock Lake filled, then spilled to the north carving the surprising grottos and labyrinth of Fly Canyon.

Fly Canyon
Beyond Fly Canyon the waters of High Rock joined Mud Meadows Creek and both emptied into the great Ice Age Lake Lahontan. The photo shows the narrow defile at the mouth of Fly Canyon through which the torrential Pleistocene waters flooded. Today the silence of Fly Canyon is broken only by the hushed whispers of trickling water or the occasional croak of a frog from deep within a stagnant pool.

This wilderness is a component of the Bureau of Land Management's National Conservation Lands.
