A new event highlights Colorado’s yellow-bellied marmots, with activities and voting taking place this week. The inaugural Fat Marmot Week begins Monday, focusing on these robust rodents native to high-altitude regions.

Inspired by Alaska’s Fat Bear Week, the celebration emphasizes the importance of conservation and scientific research surrounding marmots. Eight of the region’s heaviest marmots are featured, with the public invited to choose their favorite.
The event also aims to raise awareness about ongoing research by the Marmot Project at the Rocky Mountain Biological Laboratory (RMBL). Established in 1928, RMBL conducts long-term ecological studies, including detailed observations of marmots’ behavior, social structures, and responses to climate change.
Yellow-bellied marmots are squat, squirrel-like animals that spend about half the year underground in hibernation. During warmer months, they feast on vegetation to build fat reserves for winter dormancy. They are a common sight in Colorado’s mountainous landscapes, often seen sunbathing or foraging.
The Marmot Project’s research has provided invaluable insights into these creatures, tracking their populations and behaviors over more than six decades. Climate variations—affecting snow, temperature, and plant growth—pose ongoing challenges to their survival.
Funding for the project faces financial hurdles, leading to creative fundraising efforts such as OnlyMarms, a playful online venture generating funds for the research and supporting related causes, including donations to UCLA.
The digital fundraising extends into the cryptocurrency realm, with a $OnlyMarms token platform accumulating around $100,000. These efforts aim to preserve the long-term scientific work crucial for understanding climate impacts on high-altitude wildlife.
As the festivities unfold, Fat Marmot Week serves as both a fun civic event and a serious call for ongoing support for marmot conservation and research. The outcome of the contest may influence future funding and awareness efforts, ensuring these charismatic animals continue to be studied and protected amid environmental uncertainties.
By celebrating these chunky alpine residents, Colorado underscores their ecological significance and the urgent need for sustained scientific engagement to face a warming world.
