MDAS Field Trip — Mt. View Sanitary and McNabney Marsh

March 11 @ 8:30 am - 12:30 pm


We’ll begin by scanning McNabney Marsh from the viewing platform, then head over to Moorhen Marsh at Mt. View Sanitary District—one of the first water treatment facilities in the US to be developed as bird habitat. We expect to see a variety of waterbirds at these locations, from grebes and ducks to waders and peeps. Marsh passerines and raptors might also be present. This trip is great for beginners!

Hike Rating: 1 – Easy. Under 1 mile on flat terrain. Unpaved paths, potentially muddy.
Elevation change: N/A
Leader: Sandy Ritchie & Matt Tarlach

Meet: Meet at the wooden observation deck overlooking McNabney Marsh, east of I-680, at 8:30 AM.
