Pompeys Pillar National Monument is home to Captain William Clark’s signature carved into a sand stone butte along the Yellowstone River in 1806. Clark’s inscription is still the only remaining physical evidence along the route of the Lewis and Clark Expedition. - My Public Lands Magazine

Rather than cruising through the air at a constant speed, the team found that the squirrels continuously modulate their speed and direction to attain distance and lift…
