This Brackenbank and J^ewbiggin fault is known toexist for many miles eastward of the Eden ; it has also (as I believe)a considerable extension westward, in the direction of Cummers-dale. The Lower Permian beds which are cut off by these faults arethe Penrith Sandstone, a bright red rock remarkable for the scaleon which it is false-bedded, and a red shaly series overlying it, anddirectly underlying the Sandstone. The Penrith Sandstoneis well shown in the Petterill, a little below Wreay Bridge. Thejunction of the Penrith Sandstone with the overlying shaly beds (whichin this locality contain gypsum) ma
