By now the creek should be rushing, and the waterfall might be going full blast. We’ll search for insects, amphibians, and more. We will learn about an amazing fish called the steelhead that comes into the bay from the ocean and swims up this creek to lay eggs and then goes back out to sea! When the creek is full, we have to use a trail that is cut into a stone bank above the water; this narrow section can be slippery and challenging. Strollers are not recommended. We request that no animals (except service animals) attend. Heavy rain may cancel. If questionable weather, call (415) 893-9527 on the morning of the walk for a recorded message to see if the walk is cancelled. David Herlocker will lead.
