If you have spent any time researching Lake Powell, you have probably seen both names used - sometimes interchangeably, sometimes not. Are they the same thing? Here is the definitive answer, plus context that will make your next Powell trip better.
The Short Answer
Lake Powell is the reservoir. Glen Canyon is the canyon system it flooded. They are the same geographic location, but the names refer to different things - one is the water, one is the rock beneath it.
What Is Glen Canyon?
Glen Canyon was a 186-mile stretch of the Colorado River canyon system in southern Utah and northern Arizona. Before the dam was built, it was considered one of the most beautiful places in the American West - a labyrinth of sandstone walls, hanging gardens, natural arches, and side canyons with names like Cathedral in the Desert, Music Temple, and Hidden Passage.
John Wesley Powell - the one-armed Civil War veteran whose name the lake now bears - ran the Colorado through Glen Canyon in 1869 and described it with awe. Explorer Edward Abbey called it "the place no one knew" before it was lost.
What Is Lake Powell?
Lake Powell is the reservoir created when Glen Canyon Dam was completed in 1966. It took 17 years to fill completely. At full pool, Lake Powell covers 254 square miles, reaches depths of 583 feet, and has over 2,000 miles of shoreline - more than the entire Pacific Coast of the continental United States. It is the second-largest reservoir in the United States and one of the most visited recreation areas in the country.
What Is Glen Canyon National Recreation Area?
Glen Canyon NRA is the federally managed land surrounding Lake Powell - 1.25 million acres across Utah and Arizona, managed by the National Park Service. Key facilities include:
- Wahweap Marina - The largest marina, near Page, Arizona. Boat rentals, lodging, tours.
- Bullfrog Marina - Mid-lake on the Utah side. Good base for upper-lake exploration.
- Antelope Point Marina - Near Page, smaller and less crowded than Wahweap.
- Halls Crossing - Upper Utah arm, ferry crossing to Bullfrog.
Why the Side Canyons Are Where It Gets Special
The side canyons are where Powell becomes truly extraordinary. Escalante River arm, Face Canyon, Iceberg Canyon, Warm Creek Bay, Last Chance Bay - places you can only reach by water, and most visitors never find them because there is no road, no trail marker, just a canyon entrance off the main channel.
That is exactly why a detailed map matters so much. The Lake Powell Map Beach Towel labels 200+ of these points of interest - canyons, marinas, coves, beaches, and back-channel routes - so you can actually plan your exploration instead of just motoring up and down the main channel like everyone else.
Quick Reference

Whether you call it Lake Powell or Glen Canyon, there is nowhere else quite like it. 186 miles of red canyon walls, hidden coves, and blue water - and most of it remains unexplored by most people who visit. That is the whole point of going deeper.
The Lake Powell Map Beach Towel is designed for people who want to actually explore it - not just float near the marina.
