An imposing landmark on Highway 101, just south of Hopland is Frog Woman Rock (formerly known as Squaw Rock).

This was a barrier to the progress of the railroad that was following the Russian River on it’s West Bank. They could not go around the monolith so they had to tunnel through it.

This became the 1,270 foot Tunnel No. 8 on the Northwestern Pacific Railroad (NWP). While this monolith was a new delay to the railroad’s northern progress, the local Pomo people knew this location very well.

To them it was know as Bi-tsin’ ma-ca Ka-be, Frog Woman Rock.

There are various legends of how the rock got its name. One Pomo story, filtered through early settlers, is that the rock was a sort of “Lover’s Leap” featuring in a lover revenge quarrel of the scorned Sotuka. Other say Sotuka is the wife of Coyote the trickster and the Pomo people avoided the rock. While others believe when the railroad tunnels through Frog Woman Rock, it released evil spirits.

Whatever the “truth” behind the legend of the rock, it was always be hidden in the past.

In 2024, Frog Woman Rock was designated California Historical Landmark No. 549. The plaque reads:

Since time immemorial, this monolith has been revered by Pomo people as the home of Frog Woman, the consort of coyote, and a special being in her own right. For native people it is a place of sacred power and a reminder of the connection we still have with our spirituality and natural environment. The presence of this great rock on the local landscape is a solemn witness that will forever be a local symbol of our indigenous collective conscience, strength, and perseverance.
