Below is a link for a topo map you can view the area with. Use the link below and select the "large" size map when it loads for a better look. Looks like there is a sandpit to the south and a few jeep trails which lead back towards hwy 19 and probably connect to the powerlines that lead to Big Scrub? Please let me know if you do find anything thats worth going up there for.
