Larry. Roy and r descended as more clouds lapped in. Wethen commenced explorinp. the spooky Land of Luz. It is like no othercave or pit in 'lexica. The bottom measures about 60')' by 400' and islargely covered by a forest of immense (up to lOa' hip.h) trees which shadethe leaf covered floor. Lar~e blocks of breakdolo."n are hidden in the trees.A major stream Dl:'t ....ork winds acr05S the floor.

Any ambitious soul could easily make itnumber two by surveying to the high side of the entrance and di~ging precisely13feet down in the silt sump at the bottom: And Hoya de la Luz?Why it was a rousing 189 meter free drop.
