I think this is the robust variety of moss that grows at higher elevations. I first noticed it at 1,000 feet and the higher I went the more of it I saw.

This picture was taken at 1,800 feet near the north end of Lower Lena Lake in the Olympic National Forest.

It rained and snowed all day long but I was able to stay nice and warm thanks to some glowing coals that had been left behind by some campers.
