The Whirlwind Crossing Road boat ramp is located in San Juan County, Utah near the town of Montezuma Creek. It is a concrete boat ramp that provides access to Lake Powell, which is a large reservoir on the Colorado River.

According to the latest information available, the Whirlwind Crossing Road boat ramp is approximately 20 feet wide and has a gentle slope that extends into the water. This makes it suitable for launching a variety of watercraft, including powerboats, sailboats, and personal watercraft.

The lake itself spans across both Utah and Arizona and is popular among boaters, fishermen, and water sports enthusiasts. It is important to note that Lake Powell is subject to changing water levels and weather conditions, which can affect the safety and usability of the boat ramp. Visitors are encouraged to check with local authorities for the latest updates and advisories before heading out on the water.
