RMBL’s work is made possible by generous donors at every level, from a one-time gift, to a monthly payroll contribution, to a pledge to a scholarship fund, to a decades-long annual commitment, to a lump sum designated for critical projects and programs: all of these allow RMBL to continue to support the critical infrastructure, resources, and long-term data sets that make our science, education, and community programs possible. As a RMBL Explorer, giving $5,000 or more each year, you help sustain this place and the research and understanding that happen here, with special access to the people and places your generosity supports.

What Explorers Experience
Every Explorer tier includes access to a season of exclusive programs designed to bring Explorers closer to RMBL’s science, scientists, and place. A typical summer includes:

Sips & Science
Small, informal gatherings with RMBL scientists, hosted in private homes around the valley. Hear about current research directly from the people conducting it, and get to know other curious Explorers along the way.

Explorer Hikes
Small-group field outings led by RMBL scientists into the rare landscapes they study, from alpine basins to protected research preserves not otherwise open to the public.

Priority Access
First invitations to lectures, guest scientist talks, and other community gatherings throughout the season, plus behind-the-scenes updates every two weeks from our development manager.
Programs, dates, and locations vary each summer and are shared directly with Explorers each spring. See this season’s full public events calendar for a sense of what’s typical.

Not ready for Explorer-level giving? RMBL also hosts community programming that’s free or low-cost and open to everyone, including RMBL Fest, the Art/Science Exchange, the Douglass Distinguished Lecture, and RMBL Reads. See the full community calendar for what’s happening this season.
