It was a calm and warm mid-September day when my friend Jeff and I put our canoe in the water at the Rainy Lake Visitor Center boat ramp. Jeff is a park ranger at Grand Canyon National Park and I was excited to show him the sites of some of the most interesting historic events that took place on Rainy Lake inside what is now Voyageurs National Park. As we paddled away from the boat ramp the North Woods were in all their splendor. A loon dove under the water no more than 50 yards away and an eagle soared overhead. The very first hint of fall color shone on a few of the scattered aspens on the lakeshore.

The blue fluttering banner was whipping in the hot, dry, desert wind. It was easily spotted above the cactus garden. It did not signal a restricted zone but, rather, salvation. Beneath the flag was a barrel of water, or aqua. Border jumpers heading north from Mexico who couldn’t carry enough water to last through the trek would most likely find this life-saving liquid.

Long before National Geographic came up with its Trails Illustrated series of maps to the National Park System, the U.S. Geological Survey was cranking out topographic maps to the parks. Today, the USGS map collection is just getting larger.

Though it's only about a two-hour drive through the countryside from Zion National Park to Cedar Breaks National Monument in southern Utah, relatively few folks know about the monument. This short video primer provides an introduction.
