Glory Hole

Lake Berryessa, CA

The morning glory spillway in Napa, California, is the largest in the world and allows water to bypass the Monticello Dam when at capacity.  The Glory Hole is about 61m from the dam; the distance from the funnel to the exit point - which is situated in the south side of the canyon - is about 213m. The outside diameter is 22m, slowly narrowing to 8.5m at the exit (Photo from The Earth Story)

I jog around La Cité on a dark cold deserted morning and wonder, as I sometimes do, whether I incorrectly set the alarm and it is really 2AM.
