Sign at the primitive East Fork Trailhead.
One of several large avalanche paths that run to the bottom of the East Fork of the North Fork of the Big Wood.
There are several islands of shady Douglas fir forests that break up the otherwise open south facing East Fork Trail.
Typical open trail conditions out the East Fork Canyon. The trees in the background have been trimmed by massive avalanches during winter.
Avalanche trimline and a huge pile of debris at the bottom of the canyon.
This stair step waterfall can be seen from the trail about 1.5 miles out the canyon.
Close up of the stair step falls.
The view up the East Fork Canyon after turning sharply to the east at the 2-mile mark.
Sedimentary rock layers are visible in the cliffs high above the canyon floor.
Late season wildflowers interspersed among the sage brush on the open slopes of the East Fork.
The trail disappears at the creek 3 miles up the canyon. It is possible to bushwhack further into the headwater basins.
Aside from sedimentary rocks, the Boulder Mountains are also composed of intrusive and extrusive volcanic rocks.
