Hey Sean! Yes, we posted about this in our August Highlights.
Note that five of the six peaks in the San Diego challenge remain open…almost. Only the final .2 miles to the summit of El Cajon are in National Forest.
Most state parks remain open, including Cuyamaca.
Some are closed, but usually where access practically requires some National Forest travel (San Jacinto SP).
Currently ALL of the peaks in the SoCal challenge are closed, as they all fall within National Forest land. The closure order expires September 17th, though there could be extensions.
It is also worth noting that the deadline for the San Diego and SoCal challenges is December 31st.
