How to reach:
To reach the bench marks from Hydaburg, AK begin in Hydaburg on Union Street, proceed south to the end of the street, continue in a southerly direction past two warehouse buildings and to the Hydaburg city pier. The tide staff was located on the western face of the pier, on the pier extension where the Federal Aviation Association (FAA) Automated Surface Observing System (ASOS) station is positioned approximately 70.00 m (229.66 ft) from the primary bench mark. The primary bench mark is located on the northerly side of the pier where the road gravel intersects with the cement comprising the pier, set flush in concrete. The other four bench marks are located along the shoreline in prominent rocks to the east of the pier.
