Keystone Spit has not always been here, about 6,000 years ago this whole area was only a shallow arm of Admiralty Bay. When the 5, 000 foot (thick)Vashon Glacier melted and retreated from Puget Sound the sea level rose hundreds of feet. For several thousand years this rising water eroded coastal bluffs that provided sand and gravel for building beaches along Whidbey Island. This process continues today.
Three thousand years ago wave action called littoral drifts caused the spits to form and grow towards each other until they finally connected. This action form what is know as Keystone Spit today.
Today Keystone Spit is a mile-long narrow gravel bar that separates Admiralty Bay and Crockett Lake. Crockett Lake is a large saltwater marshland that was formed as the sand bar grew together. Today a major portion of the spit is open for public enjoyment as a place to beach walk, bird watch, fish or fly kites.
