Trail Ridge, the largest of several long, low north-trending ridges in central Florida, is among the most distinctive landforms in this area of low topographic relief. The ridges are complexes of sand dunes formed during the Pleistocene, when the coastline was some 300 feet lower than it is today. The sandy sediments were eroded from rocks of the Appalachian highland to the north. Some of the ridges are mined for the industrial minerals rutile and ilmenite, sources of the titanium metal used in the spacecraft operated at Cape Canaveral on Florida's east coast.
