Deep in the forest, I came upon a bear "stomp trail", which is a trail of indents made by thousands of bear paws hitting the same spots as the bears walk. Bears use these stomp trails to imbue the ground with their own scent from their paw pads.
The astounding part is how many species use trails where bears leave their scents. In this case, one example was a pair of mountain lions. They are a male-female pair who were probably together for a few days while the female was in estrus.
Check out the mountain lions and other species in the video. It's cool to see so many in one spot.
