Geology Talk (30 minutes) South Rim Village: 3:00 pm

Geology Talk is a free, ranger-led program held at the Yavapai Geology Museum on the South Rim, covering how the Grand Canyon actually formed: the layered sedimentary rock exposed in the canyon walls, the uplift of the Colorado Plateau, and the roughly six million years the Colorado River has spent cutting through it. The 30-minute talk is pitched at a general audience and needs no advance sign-up.

What to expect

• Meeting point: in front of the Yavapai Geology Museum, South Rim Village
• Length: 30 minutes
• Cost: free
• Accessibility: wheelchair accessible, including the paved path from the parking area up to the museum

Good to know

Exact meeting times shift by season and by year, so confirm the current time at any visitor center, on posted schedules around the village, or the NPS Grand Canyon calendar before building your day around it. Like other outdoor ranger programs here, it can be canceled on short notice for lightning or severe weather, in which case it may move inside the museum.
