We lived at the top of the old road leading down to L'Esperance, a Danish sugar plantation in the late 1700's and early 1800's. This link has a description of the hike.
The "foundation of an old house" mentioned is our old pre-fab national park service house foundation, the house blown away in a hurricane. The text doesn't mention the graves at L'Esperance; a large flat marker for Hendrick Tonis was there. My brother Bill mapped the whole area and cleared out saplings so that one could see the foundations of the old buildings and mills. We looked down on the royal palm from our house.
