Mexican black bear mom and cub scale canyon wall like pros

In late March, Stephanie Latimer was kayaking down the Santa Elena Canyon in Texas’s Big Bend National Park when she spotted endangered Mexican black bears scaling a rock face.

"Mommas with children or cubs — don't try this at home," she posted on YouTube.

The incredible (and sometimes suspenseful) clip of the daring rock-climbers has since gone viral.

"The mother bear managed the vertical climb with ease, but the cub had to make some impressive and daring spread eagle moves to scale the steep rock face," wrote TIME's Melissa Locker. "Give him a few years, though, and he will undoubtedly be able to make the climb with a picnic basket in one hand."

Those of us without paws, however, should probably stick to using harnesses and ropes.

Mexican black bears were once common in the region, but "human interference" nearly wiped them out in the early 20th century.

Even after the bears started to repopulate the park in the 1980s, there are still only a handful who call it home.

The National Park Service estimates there are only eight to 12 adult Mexican black bears currently living in the park.
