Coleman carried a most impressive botanical reference manual up to 8000 feet, his signed first edition of:
Flora of the Pacific Northwest
An Illustrated manual
by C. Leo Hitchcock
and Arthur Cronquist
Burroughs 3 is one of my favorite spots to go on an early morning in August or September. It is a quiet spot with a quite of view of Mount Rainier. It is a good walk from Sunrise , maybe 3 miles and with ups and downs maybe 2000 feet of elevation gain.
It's one of the easiest ways to get to 8000 feet in Washington State.
