Lake Berryessa black hole
The Glory Hole... Freaky

Astronomy 10 learning goal Q10.1
This glory hole is fed by overflow water at Lake Berryessa, west of Woodland, CA.   There is something to be said about a possible primal fear of black holes and similar phenomena, as some children find watching the water going into this glory hole very disturbing.   A University of California at Davis graduate student fell into this glory hole in the mid-1990's.
