A remote pocket of Boulder County turned into an active investigation zone when a black bear reportedly attacked a person near Beaver Reservoir, a high-country lake about 15 miles northwest of the city of Boulder. Colorado Parks and Wildlife officers and Boulder County deputies responded to the call, and the person was reported injured. Officials are asking people to steer clear of the area while wildlife officers sort out what happened.

Officials respond

Colorado Parks and Wildlife said it was responding to a reported bear attack near Beaver Reservoir and was working with Boulder County deputies to secure the scene and look for any additional public safety concerns, according to The Denver Gazette. Regional CPW accounts are being used to push out updates while officers assess the situation and decide on next steps.

Where it happened

Beaver Reservoir sits high in the Front Range foothills and is reached by rough forest roads and trails, which can make emergency responses slower than along the more developed Front Range corridor. Mapping data places the reservoir in a sparsely populated part of Boulder County that sees dispersed camping and hiking during the summer. Those conditions can make it harder to track down witnesses and locate animals, so visitors are being urged to stay away for now while investigators do their work, according to Mapcarta.

Why bears are showing up

Wildlife managers say that while black bear attacks on humans are rare, dry conditions and poor natural food sources can push bears into the same spots people like to camp, hike or cook outdoors. That mix has led to an uptick in human-bear reports across Colorado as bears look for easy calories like trash, pet food and unattended cooking gear, according to Colorado Outdoors.

Context and recent cases

When a bear is considered an ongoing threat to people, officials have sometimes opted to euthanize the animal. In a separate case this month, wildlife officers located and killed a bear believed to have attacked a camp staffer at Glacier View Ranch near Ward, a reminder of the tough calls managers face when conflicts escalate. The Glacier View incident was reported by Denver7.

How to stay safe

Colorado Parks and Wildlife advises people to give bears plenty of space, secure food and garbage, make noise on trails and report aggressive or repeated bear activity to wildlife officers. If a black bear does attack, officials say people should fight back rather than play dead. Backcountry visitors are encouraged to remove attractants from campsites, keep pets leashed and check agency updates before heading into remote areas.
