This is a science book wearing hiking boots. If you're actually heading to the Grand Canyon, it's a fantastic way to upgrade the experience from 'looking at rocks' to 'reading a planet's history.'
However, because it's over 20 years old, treat the logistical advice like a historical artifact. Use it for the geology, but use your phone for the permits and the shuttle schedules. For a kid who loves rocks or 'how things work,' it’s a solid, non-fiction pick that respects their intelligence.
