HIGH COUNTRY Screening at Sugarloaf Ridge State Park

June 30, 2021

Join us for a screening of HIGH COUNTRY by local filmmaker, Conor Hagen, at Sugarloaf Ridge State Park, followed by a panel discussion with the director and Sonoma Ecology Center staff on on environmental conservation, equity, and sustainability in Sonoma Valley.


Entrenched in nostalgia, HIGH COUNTRY tells a timeless American story of how a community of conscientious and forward-thinking young people, disguised as ski bums and hippies, happened upon a ramshackle mining town on the fringe of society and worked to conserve and protect it for years to come.

Hidden amidst the high peaks of the Rocky Mountains, Crested Butte, Colorado has always been a place defined by its people. During the 1960s and 70s, this lawless frontier town provided a hide-out, an escape, and ultimately a paradise for the wandering souls who stumbled upon it. Driven by stewardship over greed, this progressive group found themselves with a blank canvas of a town in which they would create a world of their own. Since that time, Crested Butte has continued to grapple with how best to walk the line between growth and conservation – a challenge faced by small towns across America today.

Crested Butte is a unique example of a place that, in the face of economic pressures, has managed to maintain its strong sense of character. The goal of this film is to share the story of one town, in the hopes of inspiring community amongst others.

It’s a film about how if you don’t take care of a place you risk losing it forever.

Watch the trailer.

Star Parties: Presentations on astronomical topics are given in the classroom throughout the course of the evening. Starting at dusk, the Observatory’s three main telescopes are open for your viewing. Docents set up additional telescopes in front of the building. Friendly and knowledgeable docents are available to answer your questions.


  1. Map and Directions
  2. When to arrive: We keep the observatory open as long as there are visitors, but you must arrive within 3 hours after start time to ensure that we remain open for you. Summer Star Parties begin with tours and presentations until it’s dark enough for observing.
  3. Bring warm clothing, even in summer—observing is done outdoors.
  4. There is a short walk from the parking area to the Observatory and you may wish to bring a small flashlight.
  5. White Light: No white lights should be used after dark; the observatory is a red-light-only area to protect everyone’s night vision. We will supply red cellophane to cover flashlights. Please note:
    ◦ Bring a SMALL flashlight (large camp lanterns, light sticks, etc., cannot be adequately covered by red cellophane).
    ◦ Cell phones or cell-phone flashlights are acceptable but must be covered in red cellophane. (No cell service at the observatory).
    ◦ Some head lamps are difficult to cover with red cellophane. Once covered, head lamps should be worn around the neck or used pointing down as they are usually very bright at eye level.
    ◦ Red flashlights are available for $5 at the observatory.
  6. Alcohol is prohibited on Observatory grounds.
  7. The Observatory is not open to the public except for scheduled events.

Classroom presentations are always offered on Star Party nights even if the weather is poor. For current conditions call the observatory at (707)833-6979.
