In late September I will heading to the North Cascades, staying in a town called Glacier for 2 days. I'm going to Heather Meadows to photograph Mt. Shuksan from Picture Lake. According to VZW coverage locator there's no coverage in Glacier but there is something at the ski area of Heather Meadows. Can anyone confirm this assertion? After Glacier I'm traveling to Marblemount for a few days to visit Diablo Lake and Ross Lake NRA. VZW appears to cover the mentioned areas. As for ATT Wireless, its website states that no coverage is available either at Glacier or Heather. Of course, a coverage report will be available once I get back but if anyone can shed some insight on the these areas it would be great. I'm looking to avoid making satellite calls if at all possible. Thanks in advance.
