I totally forgot to post pics from the Lake Jackson Indian Mounds in Tallahassee! This park has seven mounds. We walked to the top of this one:
About thirty minutes from Tallahassee are the Letchworth Mounds, and one of them is the tallest in Florida – we didn’t go to those, but maybe next time.
There is a really good site for mounds in Mississippi that the National Park Service has – it’s here. It doesn’t list all the small mounds – which is probably pretty close to impossible to do anyway – but it has a map and description of all the large ones.
