With snow at higher elevations, we decided to do a short hike out near Roosevelt Lake, near Hawk Creek Campground 30 miles upstream from Grand Coulee Dam. The trail leaving the day use area disappeared quickly, but we were able to continue along the sandy shore and then over land for several miles. There was a dark cave up above the lake, but we did not venture inside.
Mika enjoyed running free in the desolate open space, but when she started limping we found a prickly pear cactus in her paw. After pulling it out, she was as good as new.
