The Roaring Fork Valley is black bear country, so trash is the main issue
If you move to the Aspen area, you are moving into black bear country. The valley’s mix of aspen groves, Gambel oak, and berry shrubs is exactly the food-rich habitat black bears like, so seeing a bear in or near town is a normal part of the year here, especially in late summer and fall when bears are eating heavily before winter.
The main thing that turns a passing bear into a problem is human food. A bear that finds an easy meal in a trash can, a bird feeder, or a parked car can learn to come back, and a bear that keeps seeking human food can end up being killed. So the most useful habit is also the simplest: keep food and garbage where bears cannot reach it. Colorado Parks and Wildlife urges people in bear country to use bear-resistant trash containers and to secure attractants, and local trash rules in the valley are worth checking when you move in.
For residents that means using bear-resistant containers, not leaving trash out early, bringing in feeders and pet food, locking cars, and closing ground-floor windows and doors. Most bears that wander through neighborhoods cause no harm if they find nothing to eat.
For practical steps and current guidance on living with bears, see the Colorado Parks and Wildlife “Living with Bears” page.
