Point Pogibshi, Kachemak Bay

by | Jun 13, 2023

Point Pogibshi is a prominent flat-topped grassy headland with rocky sides about 50 feet (15 m) high on the southern shore of Kachemak Bay, roughly 20 miles (23 km) southwest of Homer and 5 miles (8 km) north-northeast of Nanwalek, Alaska. The point features a navigational aid: a light mounted on a skeleton tower with a diamond-shaped red-and-white daymark. The name derives from Russian for “Point Peril” and was first published by the US Coast and Geodetic Survey in 1943. It probably refers to the wave-eroded underwater platform extending about 0.5 miles (0.8 km) from the headland; this shallow reef is marked by a thick canopy of bull kelp. The headland also accelerates the strong tidal currents that flood into Kachemak Bay. Along the southern coastline, this current is often exacerbated by accelerated winds and wave-generated nearshore currents, creating whirlpools and rips. The headland consists of bedrock from the Pogibshi formation, which developed during the Early Jurassic period (about 200 million to 175 million years ago) and is exposed at several locations on the east side of Cook Inlet. The formation comprises volcaniclastic rocks such as breccia, conglomerate and sandstone interbedded with small amounts of limestone, coal, and tuffaceous argillite.

The US Coast and Geodetic Survey ship Carlile P. Patterson charted Alaskan waters between 1883 and 1918. Officers aboard took interest in local ethnography, as the Patterson operated in traditional areas of Tlingit, Haida, Chugach Sugpiaq, Alutiiq, and Aleut peoples. Albert P. Niblack, a naval officer who served two tours, authored the book “The Coast Indians of Southern Alaska and Northern British Columbia“, published by the Smithsonian’s National Museum. In the late 1890s the Patterson took hundreds of soundings in Kachemak Bay with a Sigsbee machine while making triangulation measurements and topographic surveys. One report noted that over 30 wildflower varieties—including sweet peas, violets, columbines, flags and water lilies—were found within three or four acres at Point Pogibshi, suggesting a microclimate. Soundings confirmed the point extends 0.5 miles (0.8 km) into the bay’s currents, causing severe turbulence hazardous to small boats. On January 30th 1999 the fiberglass cod-fishing vessel Kavkaz iced up and capsized near Point Pogibshi. The Coast Guard found no sign of the crew. The fishing vessel Arizona towed the overturned boat to a beach near Port Graham, where rescuers heard knocking from inside. Brothers Anton and Feodor Sanarov were trapped beneath until a hole was cut through the hull with a chainsaw almost a day later by the crew of the USCGC Roanoke Island.

Point Pogibshi marks the southern end of a mapped line extending north to Anchor Point, representing the western boundary of the Kachemak Bay Critical Habitat Area. This area of approximately 222,000 acres (89,840 ha) was established in 1974 by the Alaska Department of Fish and Game to protect habitat crucial to fish and wildlife. It is now also a shorebird reserve and an estuarine research reserve. In the mid-1980s scientists from around the Americas documented serious population declines in shorebirds, prompting the scientific community to develop a framework for a network of key sites to protect shorebirds and their habitats. This resulted in the Western Hemisphere Shorebird Reserve Network. In 1995 Kachemak Bay was designated a network site; it was expanded in 2016 and now includes 232,461 acres (94,074 ha). In 1999 the bay was designated a unit in the National Estuarine Research Reserve System, protecting more than 370,000 acres (149,733 ha) of diverse coastal ecosystems including marsh plants, marine algae, animals, coastal communities and fish habitat. Kachemak Bay is the largest of 30 reserves in the national program, which focuses on long-term research, water-quality monitoring, education and coastal stewardship. Daily management and oversight are provided by the Alaska Center for Conservation Science. Read more here and here. Explore more of Point Pogibshi and Kachemak Bay here:

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2022 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The color scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
