Summary Author: Phil Lachman
This photograph showing what at first glance may appear to be an unconformity was taken at a roadcut at Berowra, New South Wales, Australia. Actually, this roadcut shows a normal sedimentary contact between a cross-bedded sandstone facies unit and more planar-bedded facies unit in the Hawkesbury Sandstone. The lower unit is not tilted, rather the layering is a crossbedding. Photo taken on August 16, 2009. Thanks to Marc Hendrick for his help with this.
