The Grand Canyon: One of our Nation's greatest treasures. Majestic. Immense. Dynamic. Dangerous. Epic. To capture the essence of the Grand Canyon, you must experience it first-hand. The following mapbook is composed of high detail, hill shaded USGS topographic maps overlaid by GPS captured hiking trails and waypoints. USGS topo maps have been used for over a century in the adventurer's pursuit of the outdoors. These topo maps are digitally scanned at high resolution, then cropped to 1:12,000 scale providing more detail for simple, more accurate navigation (original USGS topo maps are scaled at 1:24,000). Not only are these maps an excellent accessory for a GPS unit, but also work well with a magnetic compass (still essential to any hiker's tool set). In order to provide the most up-to-date maps available, MooseTrak Maps monitors trail hazards and conditions. Updates are provided to this publication regularly. Whether hiking rim to rim or enjoying a few day hikes, we know this mapbook will add to your enjoyment of the Grand Canyon
