Finally good weather for a change. Extremely rewarding for such a small effort, but such a long drive (3 hrs from Seattle). No wonder the crowd. 7 miles RT, 2000 ft gain. 3 hrs is probably enough for the hike, but allow a couple of hours to explore: take photos, and yes, pick huckleberries. 
Below the butte (which grants a 360° view of more fine peaks) is the Yellow Aster meadow: a patchwork of small glistening ponds and huckleberry meadow, the only camping area. What a fine site, stunning views of both Mt Baker and Mt Shuksan, perfect to explorer many surrounding small peaks, and maybe to retrace back for 2 miles and hike to Tomyhoi Lake (looks pretty big on the map). Another trail 2 miles farther drive (on worse gravel) leads to Twin Lakes. Extremely window all the way from the meadow up to the top. No yellow aster at this time. The huckleberry leaves are shining brilliantly under the sun.
Direction: From Glacier Public Service Center, follow Hwy 542 ~12 miles. Turn left on FS#3065 (Twin Lakes Road, just beyond the Department of Transportation's Shuksan maintenance facility). ~4.5 miles gravel road to the Tomyhoi Lake/Yellow Aster Butte Trailhead. Watch for mining trucks!
