Our contribution to the plethora of caches in this wonderfully scenic area.
The Crawford and Flaxman Valleys have recently been determined to have been created by more immediate means than wind and water. Both sites exhibit rock specimens with shock metamorphism and other geological features characteristic of the impact of an object of astronomical proportions.
The structures include an 8.5km long elongate crater (Crawford), interpreted as the product of a very low angle NNE-directed grazing impact, and a nearby 10km long structure (Flaxman) considered most likely to be of secondary origin, resulting from down-range ricochet of part of the projectile. These sites form part of an extensive (230x30km) NNE-trending corridor of similar elongate features and breccia zones, which may also include the Barossa Valley.
The actual sites have been identified as follows.
…Crawford (S34 43', E139 02')
…Flaxman (S34 37', E139 04')

The cache container resides in a stump overlooking the Crawford Crater. The airstrip next door is nearly aligned to receive that long ago incoming.
