Here’s a “Lost in the Woods” story with a happy ending. Colorado family returning from vacation in California detoured off I-15 into the Arizona Strip for quick visit to North Rim, bogged down in mud and snow 40 miles into the backcountry. Father and son hiked 20 miles back out to call for help and local Sheriff’s deputies, BLM and Park Rangers combined to locate and rescue the rest of the family. A couple of lessons here. First is “inquire locally.” Don’t venture into unfamiliar terrain without stopping by nearest convenience store, bar or preferably the local ranger station to ask for directions, road conditions and weather report. (On that last point, I would expect Coloradans to be familiar with the relationship between altitude and temperature. Might be sunny and warm in Southern California, but the North Rim of the Grand Canyon is up above 7,000-7,500 feet. As a rule of thumb you can expect temp to drop about 5 degrees Fahrenheit for every 1,000 foot gain in altitude.) Finally, as a hidebound old paper map & compass geezer, let me caution you youngsters about becoming over-reliant on your new-fangled electronics. This Colorado family was misled by their “smartphone” mapping, which led them onto an unpaved road impassable in wet weather. Then, when their SUV got stuck, they found themselves out of cellphone range.
