We will be going again and will not be part of a tour group so we will be able to spend some time there. The problem is that it is monsoon season and it probably will be too uncomfortable to go there before fall. Hopefully when we go the river will not be so high and we will be able to cross on the rocks.
This looks like flats made with cells, held together with zip ties and somehow fixed to a 2x4 frame. There is a grid-like pattern over the dirt that looks like ½ hardware cloth or bird-netting. Now that it is on my computer; I can zoom in and see it better than I could in person☺
