Air quality still a little smoky in Waterton today but not bad. Burned areas are present over much of the trail but Bertha lake is still pristine. Burned forest areas are filling up with thimbleberries, colorful fireweed, and other plants and the views of Waterton lake and the surrounding mountains are opened up. Trail is very busy and it is difficult to get a photo without someone walking into it but I had no worries about bears or injury with so much potential help available so there’s the silver lining. Don’t let the burned areas keep you from doing this one. It is still well worth the trip.
