have preferentially weathered leaving behind imprints of where they once lay. These continue upwards until reaching the point where much larger portions of sandstone have been removed exposing honeycomb structures and large overhangs in the sequence. These are mainly as a result of modern-day flash flooding within the gorge, however the preface to this modern analogy also comes as a result of past channelization exposing the surfaces, as we know that the area is heavily influenced by fluvial channels. Within these upper beds the sandstone also undergoes a distinct colour change moving from a red to yellow to white sandstone, as a result of leaching and weathering processes. The higher up and further away in the Warang Sandstone, the more trough cross-stratification is observed. This becomes most noticeable in the White Mountains National Park as the trough cross stratification is most well preserved. The composition of the rock unit remains relatively uniform, however the amount of lithics increases the more distal from the source. The deposition of sandstone during channelization of the coastline occurred leading to the area becoming a sequence of fining and coarsening sandstone. This further buried the Betts Creek Beds allowing more compaction of the kerogen prior to faulting, and continued the build-up of sediment with each channel filled in over time. These were covered afterwards by thicker sediments that created the trough cross stratification sitting on top; in the more distal part of the Warang Sandstone the trough cross stratification increases to the point of removing all traces of channelization and a clearer flow direction. The sandstone is then cut at the top by a thin mudstone layer as denoted by the fauna growing at the contact of the Warang and Blantyre Sandstones. Blantyre Sandstone The Blantyre Sandstone is the continuation of channelization into the Jurassic. The formation is not easy to observe at a close scale, however by using Figure 2 above and knowledge of the Warang Sandstone an accurate description can be made. The channels are well preserved by coarse grained infill material, these are marked by parting lineations in the lower beds, and load structures in finely interbedded silty layers. Another feature that occurs within these are mudclasts that due to modern weathering have been removed to the point of having, what appear as, large gouges in the rock face. Within the upper part of the Blantyre formation trough cross stratification is present,
