08/08/19 to 08/11/19, probably began a few days earlier.
Far too many butterflies to count on Donner Summit.
On highway 80 between Soda Springs and Donner Lake Interchange, it is like clouds of butterflies. They seem to be at particular altitudes, rather than height above ground.
There are many in our garden as well almost all day for the last week.
