Mountains Majesty: On the Summit with John Fielder exhibit at History Colorado Center in Denver, Colorado
My Colorado 3D Topographic Maps are used as supporting locator maps at the Mountains Majesty: On the Summit with John Fielder exhibit at the History Colorado Center in Denver, Colorado.

The exhibit will be shown from JAN 24, 2026 - JAN 10, 2027
