Merced

The slide has completely covered highway 140 and extends out into the river. Large boulders have rolled into the river creating a more interesting rapid than was there before.

The road detour crosses the river upstream and downstream of the slide. Since the hillside may never be stable again, it seems likely that the detour will be permanent.
A line of cars wait at the downstream detour bridge while another car comes from the other direction. The wait can be as much as 15 minutes if you arrive just as the light turns red.
Low water reveals the jagged rocks in the right channel at Nightmare Island. The entrance drop just upstream is somewhat less ugly.
