Inscription. Over 100,000 years ago Angel Island was part of the mainland and the ocean was 26 miles to the west. As glaciers from the last ice age melted, sea levels rose and saltwater filled the ancient river valley below, creating San Francisco Bay and Angel Island. Looking across Racoon Straight you can see the Tiburon Peninsula, Belvedere Island, Richardson Bay and Mount Tamalpais State Park dominating the skyline.
