Sunset 8:17pm. Darkness should be about 8:45pm.
Meet at Sandstone Park in Lyons @ 5:00 pm
Leave Sandstone Park @ 5:15 pm and head to Miller Rock.
Miller Rock trailhead 25 minutes later (5:40 pm)
Enter at the Riverside trailhead, turn left at the intersections and go north and take the right finger, coming back to perhaps visit the meadow, then head back to the intersections. No plans (by me) to check out the creek spur (but I could change my mind to at least check out the condition of the spur but likely not process the rock to the creek). Head down to Miller Rock, maybe to the south meadows / to the gate at the camp then turn around and head back the way we came in.
Miller Rock - two hours?? (5:40 pm - 7:40 pm).
After Miller Rock check out Rock Creek @ 8:00 pm through ??
