At the main inlet of the lake, the collection of rocks is always changing. When water comes rushing down the Central Valley, it pushes new rocks into the upper end of the lake and rearranges the rocks that are there, revealing what was hidden before and hiding was was on top.
On our most recent visit I went to the inlet looking for round rocks. Sadly, most that I found were broken. Among the surprises there, though, was this mini-boulder. It was as tall as it was wide; it’s a big rock that I could barely move. I put my boot in the photo to give you the scale.
Yet this heavy beast was not there when I last walked in this dry part of the lake bed. The water pouring in (when it did) shoved this rock into its current place. And likely when we have another big water event, the rock will be move or buried. And something else will take its place.
Water with such force that it can move boulders and split round rocks. Someday I hope I’m there to witness this happening.
