The rocks exposed in Oyaron Hill are ancient and sedimentary in origin. The sandstones and shales of the Oneonta Formation are costal deposits (lower) and river deposits (upper) were deposited about 370 Ma, during the late Devonian Period. The sands and muds that form the Oneonta Formation derived from the weathering and erosion of mineral grains from pre-existing rocks. In turn, the Oneonta Formation rocks are exposed through later uplift and erosion by both water and ice.
Materials
Brunton Pocket Transit Compass
General Procedure
1. Measure an outcrop and carefully sketch the features exposed on the surface. Identify any small and large-scale cross bedding. Also, note any erosion surfaces cutting into “horizontal strata” or shales at an angle, which may indicate the margin of river channel cutting into floodplain sediment.
2. Using a Brunton Pocket Transit compass, take 5 directional readings on the surface of crossbeds as directed. Record.
3. After sharing the paleocurrent data among the groups, use the data to construct a “rose diagram” to plot all data on it and determine which way the river ran.
4. Using a Brunton Pocket Transit compass, take 5 directional readings on the glacial striations as directed. Record.
Results
According to the collected data of the class the river ran at an orientation of between 20 and 30 degrees to the west. ( See Rose Diagram on Lab Sheet attached)
This particular diet is very rich in protein, like most good diets in vogue today. You start the day with egg whites, consume slices of turkey with capers for lunch, eat cucumbers with vinegar and lemon for snacks, and finish the day with yellowtail sashimi with jalapeños and wasabi. Sometimes you are allowed to have frozen yogurt.
I have to say, the actual food on this diet was
