The imаge belоw illustrаtes оne оf the structures in which sаmple X is exposed (part of the Sundance formation). Using this data with the maps you already have, what process exposed these layers? Note: On the key, the Madison Formation is the oldest, and the Mowry Formation is the youngest.  Visual Description The geologic map is overlain on a satellite or shaded-relief base image, showing the distribution of rock formations across a folded structure in a mountainous or hilly landscape. The map is tilted slightly and framed by white margins, with geographic coordinates visible along the edges. The background is a grey, textured aerial image showing ridges, valleys, and drainage patterns. On top of this is a coloured, semi-transparent geological overlay bounded by a black polygon, representing the mapped area. Within this area, elongated coloured bands curve smoothly, forming a lens-shaped, symmetrical pattern typical of a large fold. The coloured bands run roughly from the upper left to the lower right of the mapped area. They are arranged in parallel, nested strips that narrow toward both ends, indicating that the rock units are folded into a broad, elongated structure. The fold appears to be a plunging anticline or syncline, with layers wrapping around a central axis. Each coloured band represents a different geologic formation, with labels printed directly on the map such as Kmr, Kt, Kcl, Jm, Js, Jgs, TRc, Pp, Pt, and Pa. These correspond to units listed in the legend. Small white numbers are scattered across the bands, representing structural measurements such as bedding dip angles, showing values like 25, 30, 35, 40, 67, and 74 degrees. Thin black lines with arrows show the orientation and direction of geological structures, such as fold axes or bedding strike and dip. Legend: In the lower left corner is a legend with coloured boxes and formation names: Mowry Formation (Kmr) – green Thermopolis Formation (Kt) – light green Cloverly Formation (Kcl) – reddish-brown Morrison Formation (Jm) – peach or light orange Sundance Formation (Js) – yellow Gypsum Springs Formation (Jgs) – light blue Chugwater Formation (TRc) – orange Phosphoria Formation (Pp) – dark blue Tensleep Formation (Pt) – pale cream Amsden Formation (Pa) – light grey-blue Madison Formation (Mm) – very light grey Map elements A north arrow is shown in the upper right corner, pointing upward. A scale bar at the bottom right shows distances in kilometres, with markings at 0, 0.5, and 1 km.
