Searching for Caves!

Spent a lot of my time hunting this fall in the Blue Mountain area. I had my tracker with me and it maped every road and trail I took. The only valley we did not exlore was the Blue Mountain Brook one. I figured the valleys would be the best places to start with because of nearby watercourse erosion and possible natural cave formations at the same time. While hicking with Andrew and Alex, we encountered many beautiful areas and plenty of rock cliffs and outcrops....but no caves. We usually tried to start from the top of the mountain and walk down to the Tobique River. Blue Montain is alo a very large area with rough terrain so caves may indeed by found but it would be nice to reduce or simplify the search. A drone would come in handy to better scope out the area and avoid some nasty hikes.
