McGowan Peak viewed from the west (June 1991).
The approach up McGowan Creek encounters serious stream flows during the Spring runoff.
The McGowan drainage is typical of most Lost River Range drainages where water will often disappear underground. You will find good game trails in parts of the drainage and thick brush in other parts, but the walking is generally good.
Once you climb above the forest canopy, the route opens up.
You will have a couple of easy rock steps to climb along the way.
