Later after charging her phone at the cabin, she examined the photo and perceived a figure standing behind a tree looking toward her.

Hiking family finds possible track off trail outside Estes Park

A family of four was hiking and identifying animal tracks in a forested mountain area when the husband found a single large footprint off the trail. The print was about 13.5 to 14 inches long and about half an inch deep, with possible toe impressions, and crossed perpendicular to the trail. The husband could not leave a comparable impression in the same vicinity. The family photographed the print with a boot for scale, felt uneasy, and continued on without seeing or hearing anything that could have made it.

Notes from the Colorado BFRO Expedition

During a daytime hike up a drainage on 10 Sept, the witness stopped at an old hunting camp and heard two clear wood knocks about 150-200 yards away. After confirming by radio that no other participants were nearby or knocking, the witness knocked back and received an immediate two-knock reply from slightly farther away. Further knocks and whoops over about 30 minutes drew no additional replies, and no movement or odor was noticed. The witness then returned to camp and later revisited the area by ATV with others.

Possible tracks found by snowshoers near Steamboat Springs

The witness and a companion were snowshoeing off trail and became stuck in a steep ravine. They found a trackway of large human-like footprints with a long stride ascending a very steep slope through deep snow. They judged the tracks unlike deer, elk, bear, or human due to depth, stride, and lack of drag marks.

Hikers find large footprint and unidentified droppings

Two people walking a dog on a trail noticed multiple large human-shaped droppings along the uphill side and discussed them as possible territorial marking. After turning back when a deer startled them, they found a single deep, clear footprint partly hidden by branches and photographed it with a shoe and water bottle for scale. They searched briefly for a natural cause for the impression but left quickly because the companion and dog were agitated.
