History of the Barrier Islands of St. Andrews Bay from SAND IN MY SHOES by John A. Burgess (1986~ with information provided by Marlene Womack)

1827: John Lee Williams described three islands off the peninsula south of Grand Lagoon. SAND ISLAND, a one mile long grassy barren, was separated from the east end of the peninsula by a narrow 8 foot channel and a shoal. East of that was six mile long HUMMOCK ISLAND with dunes on the west end that made a safe harbor on its north side. The third one, CROOKED ISLAND, was said to be the largest, six miles in length and covered in pines.

1851: A hurricane washed away all three islands, leaving only two mile long HURRICANE ISLAND.

1855: A map of Hurricane Island by Bach and Gerdes shows a similarity to the old Hummock Island. The east end contained 40 foot high dunes known as the Saddle Hills. In 1986,their eastern tip location of 30 degrees, 4 feet and 23 inches corresponded with a point in the open ship channel one mile east south-east of Land's End (present day filled Old Pass on Tyndall). This appears to be the location of the Union Navy's blockading squadron camp established during the Civil War. In the late 1800s , a pilot house was built on the east end of Hurricane Island. Continued erosion of Hurricane Island resulted in the island going from two miles in length to one and one-half miles. In 1917, the pilot house was moved to bay side of the island.

1926: A hurricane washed Hurricane Island clean.

1934: HURRICANE ISLAND had ceased to exist.
