1. Prepare a geologic cross section of the Gateway Colorado map. Use an EW line in townships 35 and 36 passing through the peak at 7045’. This exercise involves three steps:
(1) Prepare a topographic cross section along the line
(2) Add the geologic contacts where they occur on the line
(3) Interpolate the contacts between units to make the geologic section.
The best way to make a topographic section is to lay a piece of paper along the cross section line and mark the elevations with labeled tock marks. Transfer the line
2. Prepare a geologic cross section alont A-A’ of the geologic map of Dinosaur Monument
(Utah-Colorado). You can be very rough with the topography. a. What type of fold is this? i. Are the rocks older younger as you approach the fold axis
Note: P is Pennsylvanian, the “P” with double lines is Permian, M is
Mississippian, Tr is Triassic, J is Jurassic, and K is Cretaceous. ii. Is this fold symmetric or asymmetric? b. Consider the Mitten Park and Island Park Faults i. Assume they dip to the northwest, which side the hanging wall, which is the footwall ii. Which side has moved up and how do you know?
iii. What type of fault are these? iv. What type of stress state produced these faults – extentional or compressional?

1. Sketch a paired syncline and anticline with an axis trending N-S and plunging gently to the North. Show a cross section with strike and dip symbols (no dip angle necessary)
2. Know fault types: Normal, Thrust or Reverse, and Strike Slip. Draw three block diagrams showing the relative magnitudes of the principal stresses that produce the three types of faults. Note the hanging wall and footwall.
3. Apparent dip: A set of layers has an orientation N 45 E 75 SE. A vertical road cut runs N 10 W. What is the apparent dip of the layers? Include a sketch.

Study Guide – Soil Origin
1.
Be familiar with all the terms on the first four slides of SoilOrigin.pdf (eg Colluvium,
Alluvium, Aeolian, Lacustine). Be able to describe these deposits in terms of composition, spatial pattern, gradation, stratification, anisotropic flow and mechanical properties, density, and deformability)
2.
Be prepared to produce a diagram illustrating the appearance, location, composition, and consolidation of supraglacial and subglacial deposits. See SoilOrigin.pdf for definitions
