Botany on the Batholith

2026 Native Plant Rendezvous
June 26-28 ~ Homestake Lodge near Butte
Join us June 26 through 28 to explore botany on the batholith! Our base will be at Homestake Lodge just three miles off I-90 on a well-maintained gravel road. The Lodge is nestled beneath the Continental Divide and within the Boulder Batholith, an inspiring setting for plant lovers and geology enthusiasts alike. The plant mascot is Sulphur-flowered buckwheat, Eriogonum umbellatum.

Registration is limited to 175 people and will be online only. After June 10, if there’s room, we’ll register people late, but it will cost more to register late and meals will NOT be available. No refunds after June 10.

Roads & trails traverse the property, which include Lodgepole-pine & mixed Douglas-fir forests, sagebrush meadows, and a large riparian willow corridor and wetlands.
Built in 2007, the Lodge is where we’ll have check-in, possible late registration & sales, and is where the dorm rooms are. For meals & meetings, we’ll gather outside in the Pavilion. The Pavilion has removable siding, and even heaters that we can use if the weather’s bad.
COMMUNICATIONS – Cell service is very limited in the area; Wi-Fi is available inside the main Lodge.

LODGING
DORMS – Inside the Lodge, the women’s dorm room has 12 beds and the men’s has 5 beds. You can sign up for these during registration on a first-come, first-served basis. There are bathrooms with showers in the Lodge basement, and there’s limited refrigerator access for dorm guests. Beds come made up with mattress pads, fitted bottom sheets & pillows with cases, but no blankets or top sheets. GUESTS NEED TO BRING THEIR OWN SLEEPING BAGS AND TOWELS.


CAMPING – The camping area is an open meadow/forested area, accessible by road and featuring porta-potties & wash stations. There are no electric hookups or dump stations. This is Pack-It-In/Pack-It-Out camping. Campers will drive to the site on the primitive road, camp in marked spots, and return to the Lodge area via a walking trail.
Camping is restricted to the areas specifically designated by the Lodge. The Lodge has a general “No Generators” policy, but you can use a generator during the day for short periods, e.g., to cool a refrigerator.
It’s a 10-to-12-minute walk from the camping area back to the Lodge on a single-track, undulating trail. People might consider bringing a sturdy bicycle for the commute. While it’s possible to drive your vehicle back & forth, parking could get congested at the Lodge. If you have mobility issues and concerns about using the trail, please contact the organizers to make alternate camping arrangements – we have options!
OTHER ACCOMODATIONS – Butte is just 15 miles away with motels, vacation rentals and commercial campgrounds. Summers are increasingly busy, so book early! Find lodging ideas at visitbutte.com/stay/

THE BOULDER BATHOLITH
The Boulder Batholith is a mass of ancient granite 3-to-4-miles thick that forms much of the landscape between Butte and Helena.
It started out as molten rock deep underground about 75 million years ago, created by the same forces that built the nearby Elkhorn Mountains.
Over time, erosion stripped away the overlying layers and exposed and fractured the solidified granite, where it weathered into the rounded boulders and hoodoo-like formations for which the area is famous.
Besides shaping the scenery, the batholith is also the geologic engine behind Butte’s legendary mineral deposits. Its cooling magma released the hot fluids that later filled cracks with copper, silver and other metals.
Geologist Colleen Elliot will lead a Saturday field trip focusing on the geology of the batholith.
