ANAN WILDLIFE OBSERVATORY RECONSTRUCTION

THE ANAN WILDLIFE OBSERVATORY IS LOCATED 35 AIR MILES SE OF WRANGELL, ALASKA, ON THE

CLEVELAND PENINSULA. ACCESS TO ANAN BAY IS BY A 35-MINUTE FLOAT PLANE FLIGHT OR

90-MINUTE BOAT RIDE FROM WRANGELL. THE TRAILHEAD IS LOCATED ON THE SHORE OF ANAN BAY, AT THE MOUTH OF THE SALTWATER LAGOON. THE HALF MILE TRAIL LEADS THROUGH THE RAIN

FOREST ALONG THE EDGE OF THE LAGOON TO ANAN CREEK, WHICH IT FOLLOWS BRIEFLY BEFORE

REACHING THE OBSERVATORY SITE. THE LATITUDE AND LONGITUDE OF THE OBSERVATORY SITE ARE

APPROXIMATELY 56.179032° N, -131.883935° W.
