History came alive at South Table Mountain Park on Tuesday, May 26, with the grand opening of the T. rex Tooth Trail!

This new 1.5-mile natural surface trail connects with Fossil Trail, Old Quarry Trail, and Basalt Cap Loop to create a scenic 3-mile loop packed with prehistoric and historic significance. The trail is named after the first known T. rex tooth discovered in North America, originally found in this area in 1874. Visitors can also see the historic Colorado Amphitheater and enjoy new interpretive signage highlighting the area’s fascinating past.

The ribbon-cutting celebration featured Commissioners Dahlkemper, Kerr, and Zenzinger—plus two surprise T. rex visitors who helped make the event extra memorable! Thank you to all our staff who made this trail and event happen.
