Grand Mesa is a prominent, east-west landform capped by hard, volcanic basalt. The original basalt field may have had a surface area of up to 750 square miles, but due to extensive erosion, the present-day remnant is about 53 square miles. This remnant has a "Y-shaped" outline, with Crag Crest on the east forming the stem, and the Palisade and Flowing Park lobes forming the branches. Thickness of the in-place basalt ranges from about 600 feet near Crag Crest to less than 200 feet on the western tips of the lobes.
The Grand Mesa is most easily accessed from Grand Junction by driving east on I-70 to Exit 49 and heading south on CO Highway 65. The drive time is ~1 hour.
