Pratt Mountain via Olallie Lake
Ian and I parked at the trailhead for Pratt Lake and Granite Mountain and headed up the trail towards Olallie Lake. At the pass between Pratt Mountain and point 5566 (West Granite Mountain) we headed NW up the ridge to Pratt Mountain. The ridge was pleasant, just a little brushy, with some large granite boulders that could be scrambled in dry weather or easily avoided otherwise. The last couple hundred feet of the ridge before the summit was a boulder field, which was very unpleasant with only 6 inches of snow.
On the descent we went down the SW side of the mountain, right across another nasty, slippery boulder field which eventually led us to the pleasant meadow land east of Rainbow Lake. We met the trail here and followed it back to the trailhead.
The slick boulder fields were the only difficulties. This trip would be best either in dry conditions or when there is a good snowpack to cover the boulder fields.
