Today’s outdoor picture of the day captures one of Boulder’s most striking landmarks — Devil’s Thumb — glowing under the fresh light of spring. With its dramatic silhouette cutting into a cloud-speckled blue sky and new green growth carpeting the lower slopes, this iconic rock formation reminds us why spring in Boulder is one of the most magical times of year.
Located above Shadow Canyon near the Flatirons, Devil’s Thumb is named for its unique shape — a rocky protrusion that looks like a giant thumb reaching skyward.
