It seems that every week on the job, I experience a new “favorite place I’ve ever been.” The nature of our team’s work studying toxigenic cyanobacteria takes us to various bodies of water across Yosemite. This post shares some highlights from our past couple weeks of field work!

To the left is a photo of our sampling site above Twin Bridges in Tuolumne. The views were stunning, and I felt in awe of the beauty of Tuolumne and its waterways.

My favorite day of work so far happened last Wednesday. We drove to Hetch Hetchy Reservoir, where the San Francsico Public Utilities Commission kindly gave us a boat ride to another part of the reservoir. Once at shore again, we hiked a couple miles (including bushwhacking through some manzanita thickets!) to the creek near Rancheria Falls. At the site, we took samples of filamentous green algae, and we also took water quality samples to test for major ions. Boating across Hetch Hetchy was an awe-inspiring experience, and hiking to the falls was invigorating and rewarding.

This week, our team is sampling at various spots along the Merced River, from Wawona through Yosemite Valley to our team’s home base in El Portal. I’m excited to continue learning about and exploring the waterways of Yosemite in the coming weeks.

Thanks for reading! Stay tuned for more updates from the Yosemite toxic algae crew in the coming weeks.
