When we got to our campsite in Grand Canyon North Rim I was a bit confused about the time zone. We came from Southern California (Pacific Time) and Arizona is in Mountain Time. The thing is California is in Pacific Daylight Time and Arizona doesn’t mess with that daylight stuff – it was in Mountain Standard Time. So the times are the same. But I set my cell phone clock ahead one hour anyway. Oops. Then I set the alarm for 04:30 to make a 05:00 appearance at Bright Angel Point exactly 45 minutes before sunrise.
