Thank you to everyone who participated in a wonderfully successful Dark Sky Week! There is only one event left, plus Don’s monthly stargazing. Keep an eye out for Todd Plummer’s “All Things Night” in May. It was a pleasure getting to know so many people who support our efforts to keep West Marin dark at night!!


Date & Time TBA @ Sunset Stargazing with Don Jolley, 3rd & C St., Giacomini Wetlands Each month, on the first clear night in the week before the new moon, stargazers gather with Don Jolley in the Giacomini Wetlands & listen to his spellbinding stories about billions and billions of celestial bodies.
