A Grand Canyon North Rim Wildflower report just posted in the Wildflower Section of the Rocky Mountain Nature Photographers forum:
Just got back from the Grand Canyon North Rim…the wildflowers are plentiful and gorgeous. Asters, lupine, paintbrush etc all over the roads to Pt Imperial and Cape Royal. The Tall Evening Primrose is plentiful and as pretty as they get. Its outta the way, but if you’re passing through soon, definitely worth the side trip.
