Tully Valley Essay

Introduction During the Silurian period, approximately 420 million years ago the rock bed central New York sits on was formed. In comparison the soils in the area only date 12 to 14 thousand years back in comparison. This resulted because archeological evidence shows that the Tully Valley as we know it today used to be underwater 500-300million years ago (Baldauf, 2003). One effect of this is there are a lot of trapped salt minerals that built up over the years and lithified to become rock. During the last glacial event about 8,000 years ago Tully was cut into the “U” shaped valley we recognize today. After the warming event and the ice receded moraines and kames, glacial land forms became visible in the till left in the valley. The Tully was a lake for a while similar to the Finger Lakes running north to south (Baldauf, 2003). Contrarily to the Finger Lakes the Tully Valley sits higher above sea level and it eventually drained. Today only two main creeks are the only remaining water in the valley, Rainbow, and Rattle Snake which flow along the 1200ft incline. The purpose of this lab is to gain a greater understanding of the factors that contribute to the phenomenon of mudboils and the causation behind the 1993 Bare Mountain landslide in the Tully Valley region of New York and its effects on the surrounding Onondaga area.

The worst started between 1878 and 1985 when solution salt miners started to drill in the Tully Valley brine field located in Onondaga County. Started by Solvay Process Company, it soon became the site of 162 wells. Many companies followed this lead using reckless extraction techniques including wild brining, and uncontrolled air padding to create interconnected multi-well caverns with large, unsupported roof spans (Sanford, 1996). Not unexpectedly the results of these practices paved way for multiple sinkholes widespread subsidence, and increased mudboil
