Reports have it that since the 15th of this month, the spring rains have been enough to intermittently cue the gloryhole. Apparently this opening of the glory hole stands as a local seasonal milestone, like the coming of the robins back home or the breaking of the ice in the north. What is a gloryhole? The massive overflow pipe that stands next to the dam at Lake Berryessa. When the “lake” (it’s an enormous manmade resovoir wherein the hills have been filled with drinking water) breifly exceeds the level of the 28 story overflow pipe, the water spills down it in a sort of circular waterfall. It looks like a hole in physics. Below are pictures of the dam and the spillway during normal water levels, and after a rainstorm.
