Entry No. 40 — the Butte file — filed under: after-dark
Montana Learning Center — Rice Astronomical Park
On the dark shore of Canyon Ferry Lake, this education center runs three observatories collectively called the Mike and Lynn Rice Astronomical Park, including a 32-inch telescope billed as the largest public-use scope in Montana. Public "Beyond the Big Sky" stargazing nights run one weekend a month from June through September, each opening with a talk from a guest astronomer before you look through the scopes. You can also book a private 90-minute "Create Your Own Star Party" (May through October, weather permitting) led by the center's executive director. The lakeside site sits well away from city light domes, so the Milky Way is genuinely vivid.
The story
Eighty miles northeast of Butte, on the dark shore of Canyon Ferry Lake, sits what looks like a modest educational camp. But step behind the main campus buildings and you’ll find the Mike and Lynn Rice Astronomical Park—a cluster of three domed observatories holding some of the most serious optical firepower in the Mountain West. Free from city light domes, the Milky Way cuts straight across the lake sky here with stark intensity.
The centerpiece is a 32-inch visual telescope, billed as the largest publicly accessible telescope in Montana. It shares the site with a 14-inch robotic setup designed specifically for deep-space astrophotography, as well as a solar system observatory housing a custom 24-inch robotic scope and specialized solar gear. Executive Director Ryan Hannahoe—who previously supported outreach for NASA’s James Webb Space Telescope mission—brings professional-grade glass and astronomical research down to lake level.
Because the site operates primarily for student STEM camps and educator workshops, you cannot simply show up on a whim. You didn't hear it from us, but you have two main ways inside: reserve a ticket for the monthly "Beyond the Big Sky" public stargazing series that runs one weekend a month from June through September, or book the big 32-inch scope for a private 90-minute "Create Your Own Star Party" led by Hannahoe between May and October.
What it's like
Arrive at the lake shore as sunset fades and the mountain air starts to cool. Public evenings open with a talk from a guest astronomer before visitors walk out to the open observatories. Volunteers from the Helena Astronomical Society and center staff operate the domes and align the optics. Stepping up to the 32-inch scope's eyepiece reveals deep-space nebulae, star clusters, and distant spiral galaxies with remarkable clarity. Dress in warm layers even in mid-summer, step carefully in the dark, and keep white flashlights turned off to preserve everyone's night vision.
The move: Reserve a summer stargazing slot, listen to the opening sky talk, then take turns peering at planets and nebulae through the big 32-inch telescope over the lake.

Good to know
How do I attend a public stargazing event?
Public "Beyond the Big Sky" nights run one weekend per month from June through September. You must reserve tickets online in advance; each session begins at sunset with a talk by a featured astronomer followed by guided telescope viewing.
Can I book a private stargazing session?
Yes, you can reserve a 90-minute private "Create Your Own Star Party" for up to 10 guests from May through October (weather permitting) for $500, which includes private access to the 32-inch telescope led by Executive Director Ryan Hannahoe.
What telescopes are housed at the park?
The park features three observatories housing a 32-inch visual telescope (Montana's largest public-use scope), a 14-inch astrophotography telescope, and a solar system observatory equipped with a custom 24-inch robotic scope, a 14-inch planetary camera scope, and a 4-inch spectroheliograph.
What should I bring or wear for an evening visit?
Bring heavy layers and a warm jacket—temperatures beside Canyon Ferry Lake drop fast once the sun goes down, even in July. Red-light flashlights are permitted, but white lights and bright device screens are restricted near the observatories.
