Well, perhaps not mountain. "Chalky Mole Hill" might be more accurate. But you'll have to climb up it to claim this cache... just be careful not to cause too much damage to the rock face during the ascent. This should be an easy grab and is very close to the road.
The cache is a small tupperware container and the hiding place should be obvious from the top of the 'hill'. Scramble up to make a quick find.
This stretch of road has a lot of heavy tyre marks and blown tyres littering the place - so be warned, obviously some street racing and tyre spinning goes on around here, so please drive carefully and avoid getting caught up in an impromptu drag race. At the side of the road there are entrances to the desert - perhaps for dune racing? The road is also 'less than perfect' in places, so watch for potholes.
