Hi,
Unfortunately I am no longer able to travel to the US and it has been 5 years since I have been to Yosemite (or in the Sierra Nevada).
I still try to follow what's going on in Yosemite, the Sierra Nevada, Utah, Nevada and Arizona as much as I can.
I found this and I think it's neat:

In a nutshell (taken from the website):
"Explore live data, observe environmental trends, investigate scientific resources, and stay up to date on physical science projects at Yosemite National Park."
Cheers from Germany!
