Over time, Morro Rock was connected to the mainland, closing off the north entrance to the bay. There are many contradictory stories as to when this occurred. The photo essay below is an attempt to tell the true story in pictures as best we can. This document is intended primarily to support docent training and visitor education for a California State Park docent-led walk of the area.

The above composite shows how Morro Bay (including the separation of Morro Rock from the mainland) has changed over the years. The left-most image is from an 1897 topographic map; the center image is from a 1981 topographic map; and the right-most image is from a 1994 satellite photograph. You will note that originally, Morro Rock was an island, and the sand spit to the south was fairly narrow and straight. After the north entrance of the bay was closed in the 1930-40's (see "progress" below), sea breaks built in the 1950's, and the harbor dredged, the sand spit took on its present form, drifting significantly to the east at its northern end. Note also the increase in the sedimentation in the bay. In 1897, the salt marsh leading out of Chorro creek formed an area much smaller than it is today. Within a couple of hundred years, the entire bay could be compromised by uncontrolled sedimentation. You can move your mouse over the above map top find "hot sport" which will take you to higher resolution images of the areas marked.

Following is a series of photos in chronological order showing the area between Morro Rock and the mainland, from the late 1800's to present. Many of these photos originate on Vic Hansen's oldmorrobay.com web site... so we direct you there to survey his entire wonderful collection.
See our "Early Post Cards" area for many more old photos of the area.
