Where did the spoil islands come from?
The Indian River Lagoon is 156 miles long and runs from Volusia County to Palm Beach County. From the 1950s to the 1960s the river was dredged to make a 12ft deep channel. This being done made 137 spoil islands throughout the Lagoon, Brevard county having 41 of those islands. On these islands you can find many different things, such as moon shells, hermit crabs, conchs, and even sharks teeth. You must have a very sharp eye to find the sharks teeth, even though they are black they hide very well in the sand. If you do come across one you are actually looking at a fossilized shark tooth that has taken thousands of years to fossilize! The teeth look black, brown, and gray from the sediment that it fell into after it came from the shark. Florida is a hot spot for fossilized shark teeth because Florida used to be under water! Many of the spoil islands can be reached in just a 10 to 15 minute paddle on a kayak.
