Officials with the Glacier Bay National Park in Alaska issued a bear advisory after two separate encounters between humans and a brown bear over the span of days.

The encounters—one of which involved a group of six hikers and the other involved two campers—prompted officials to remind park-goers to remain alert and to properly store bear attractants.

According to the National Park Service, brown bears are commonly found living in coastal areas of Alaska.

Brown bears share similar characteristics to grizzly bears, including a shoulder hump, short and round ears and a face profile that appears "dished" in between the eyes and tip of the snout.

The United States Department of Agriculture's Forest Service said people in bear country should store their attractants in bear-resistant containers and dispose of trash in bear-resistant dumpsters.

While the organization said bears recognize familiar food sources, like berry patches, streams and rivers and decaying logs that contain insects, they also remember campsites.

"While bears are attracted to any edible food, they also might try to feast on items we might not consider edible," the agency reported.

Some of these items include:

Officials said in a release issued by the National Park Service that on July 9, a group of six hikers was charged at by a brown bear.

"The group was able to deter the bear by deploying bear spray and yelling," the release said.

Days later, on July 12, two campers were approached by a brown bear.

"The campers retreated in their kayaks," officials said. "The bear remained onsite and destroyed their camping equipment."

A nearby vessel picked up the campers and brought them to safety.

It did not appear that a bear obtained any food in both situations, and officials said they do not know if both incidents involved the same bear or two different bears.

The agency also cautioned against camping in the area and recommended that park-goers remain alert.

"Two important keys to minimizing the potential for conflicts include storing food and attractants properly and keeping control of gear and property at all times as well as being prepared for bear encounters," the release concluded.

Newsweek reached out to the National Park Service for comment.

There have been other reports of bear encounters with humans.
