Resurrection Bay is considered the largest fjord of the Alaskan coast, and was likely filled with a sheet of ice as late as the LIA. Along the coast, the Pacific plate is slipping under the North American plate and moving at a rate of about 2 inches per year. This subduction is dragging the Kenai Mountains into the sea. This means Rez bay is is one of the most tectonically active areas on earth. Geologists are interested.
Much of the coast near Seward is composed of chossy greywacke. This is tragic because access to good rock becomes a challenge. If you can get out to the rock in the bay, you better prepare for waiting out rain with bear and moose.
In the south east side of the bay, including Thumb and Humpy coves, the pillow besalt offers more promising lines waiting FA's.
In the southern part of the bay and in the Gulf of Alaska there is a granite intrusion that offers the best looking rock, with the most challenging access. The Aialik peninsula holds unnamed needles upon which no human has sat. Many lines await on granite island from Taz basin, if one finds fair weather, flat seas, and lots of free time, belay from your boat.
There are reasons why climbers have avoided this area: RAIN RAIN RAIN, multi-day challenging access, expensive. Make sure you have loads of time, money, and optimism to succeed here.
Get to Seward and hike, paddle, or ride a boat to your rock of choice.
