Activation of "Sporadic-E Peak", aka South Slide Mountain, W7W/RS-019
"Sporadic-E Peak" (W7W/RS-019) is known to hikers as South Slide Mountain or, simply, Peak 6620. This 8-point summit, located in the northeastern part of Mt. Rainier National Park offers spectacular views at the end of a vigorous, but straightforward hike. Most of the route is on well-established and maintained trails, although the final 1.5 miles is on an unofficial trail. The final mile takes you across a sharp ridge to several smaller (non-SOTA) peaks before arriving at S. Slide. The 9.5 mile round trip yields about 2,500' of elevation gain.
