The following wildflowers were photographed during a hike on
Winchester Mountain with Jim Campbell and his crew,
on September 6, 2003. This hike rises above Twin Lakes,
Mt. Baker Wilderness, WA.
N 48d 57.128m, W 121d 38.133m (WGS84) at Twin Lakes,
N 48d 57.384m, W 121d 38.587m at the top of Winchester Mtn.
The elevation varied from 1590 m at Twin Lakes, to 1985 m at the top.
The summer has been hot and dry, so there were not too many flowers left, but the views were fantastic. There is no water on the trail - the only water is at Twin Lakes (I say this for the flower's benefit, not the hiker's benefit!).
