Small Rockslide closes Road in Yellowstone

Things are rocking and rolling in Yellowstone today, where a small rock slide temporarily has closed the road between Mammoth Hot Springs and Tower. The rock slide was reported about 8:30 this morning near the Undine Falls picnic ground about 4 miles east of Mammoth Hot Springs.
For the time-being motorists are being rerouted from Mammoth Hot Springs to Norris and then over to Canyon and up to Tower. It's not a quick detour, but it is scenic.
Rangers don't think there is any damage to the road bed, but want to stabilize the hillside above the road before reopening it, which they hope to do later this evening.
