Canary Springs at Mammoth is one of my favorite sites to visit. Imaging my astonishment when a return visit on Saturday showed a dramatic reduction in the flow rate from a visit two weeks earlier.
Little if any flow down the slope: Nov 13
Lots of very hot water and mist: Oct 31
The first view shows the top of the springs including some of the terraces seen in the second view. Note that there’s no water standing in the terraces. In view 2, there’s lots of water standing in the terraces. The story at Mammoth is that the total flow has stayed nearly the same over decades, while where it flows from changes rapidly.
