Why This Exists
A friend of mine drove three hours to a national park in a different state, saw a trail rated "moderate," and ended up on a Class 3 scramble with 2,500 feet of gain. The trail was moderate by local standards. For her, it was the hardest thing she'd ever done.
Trail ratings are useful, but they're local. This reference exists to close the gap between what a sign says and what your body feels. It's not a replacement for good judgment, recent trail reports, and honest self-assessment. It's a starting point so you can plan better and hike safer.
