Seldovia Point is a headland on the Kenai Peninsula at the northeast entrance to Seldovia Bay, located on the southern shore of Kachemak Bay, approximately 13.5 miles (22 km) southwest of Homer and 2.2 miles (3.5 km) north of Seldovia, Alaska. The name originates from the Russian word “Seldevoy,” meaning herring, likely referencing the significant herring population historically found in the area. These fish were extensively overfished in the early 20th century. The region is biologically productive, partly due to upwelled water from the Gulf of Alaska. This nutrient-rich water is transported by strong tidal currents into Kachemak Bay along the southern shore, supporting diverse marine life. Intertidal biodiversity is relatively high at Seldovia Point, where ocean currents transport invertebrate larvae and algal spores. These organisms settle on the diverse habitats created by the coarse gravel shorelines. The bedrock at Seldovia Point and the rubble forming the gravel beaches are part of the erosion-resistant McHugh Complex. This geological formation consists principally of basalt and chert, dating from the Middle Triassic to the Early Cretaceous period, or approximately 240 million to 120 million years ago.

Paleobotanists at Seldovia Point have discovered fossilized plants from the early to middle Miocene age, approximately 23 to 5 million years ago. Paleobotany, a branch of botany, involves the recovery and identification of plant remains from geological contexts to reconstruct past environments. So far, 75 different species have been identified in the Seldovian fossilized flora, with 51 of these found at Seldovia Point. The extensive collection efforts at Seldovia Point contribute to its comparative richness compared to other flora of the same age in the Kenai Formation. The topographic diversity of the Seldovia area during the early Miocene likely contributed to the variety of plants that thrived here. The rocks near Seldovia appear to represent channel deposits located at or near the edge of the Cook Inlet basin. The flora at Seldovia Point probably grew on well-drained slopes.

Marine biologists conduct field studies at Seldovia Point due to its diverse and abundant intertidal communities of marine macroalgae and invertebrates. During the lowest tides in summer, various species of red and brown seaweeds blanket the boulders and bedrock. The breadcrumb sponge is the most abundant marine invertebrate in the lowest part of the beach. This sponge covers the rocks and tolerates a wide range of salinity, current velocities, and powerful wave action. Read more here and here. Explore more of Seldovia Point and Seldovia Bay here:
