I loved the sign at the bottom of Beaver Brook Trail
Bottom sign:
THIS TRAIL IS
EXTREMELY TOUGH
IF YOU LACK EXPERIENCE
PLEASE USE ANOTHER
TRAIL. TAKE SPECIAL
CARE AT THE CASCADES TO
AVOID TRAGIC RESULTS
This was at the bottom of mount Moosilauke (on the north side after we had decended). Moosilauke was our first taste of alpine tree line crossing. Climb what seemed like straight up, leave trees behind and the wind was so fierce and cold at the top we couldn't stay there long.
On the very steep way down, luckily we found wooden blocks spiked into the rock face or it would have been impossible. The cascade right next to the trail was gorgeous and terrifying at the same time. One slip and you'd wash to the bottom.
