Semiahmoo Spit

age

Archeological evidence indicated the spit has developed across Drayton Harbor over the last 4000 to 5000 years (Grabert & Schwartz, 1972).

description

At the northern most reach of Whatcom County’s shoreline is a spit approximately 2000 meters long trending northeasterly from the north side of Birch Point (fig.2.). The spit separates Drayton Harbor from Semiahmoo Bay and provides some protection for small boats and shoreline developments within the bay.

width

It [Semiahmoo Spit] is only thirty to forty meters wide along its southern connection with Birch Point. High storm waves frequently overtop this area limiting access to the spit. Toward the northeastern end, the spit gently broadens to nearly three hundred meters, and appears to be quite stable.
