The largest animals on Earth, blue whales have massive bones. One rib can be longer than an NBA star is tall. Thanks to a display at an unlikely place—the Fort Bragg Waste Water Treatment Plant garage—Fort Bragg visitors can experience the enormity of these mammals’ skeletons. Whale-bone tours will run at the plant March 11–20 and are free, though donations will be accepted. See tinyurl.com/yckr5bkr for details. For those who’d rather see living whales, several whale walks will happen this March at MacKerricher State Park in Fort Bragg and Mendocino Headlands State Park in Mendocino. Meanwhile, whale videos will be shown in the geodesic Ocean Immersion Dome at the Noyo Center’s Discovery Center in Fort Bragg. Find out more information at tinyurl.com/43p6y47t.
