  1. Mill Frequency and Sediment Load in Bennington, Caledonia, and Chittenden Counties, Vermont Andrew Boule and Miles Sturm December 10, 2003

  2. How A Mill Works - The Wheel House

  3. Introduction - counties chosen for varying geography -painting of mills, dams, and ponds

  4. Methods • Looked for mills on Walling’s maps, 1856 - 1858 • Calculated mill frequency for each town (per square mile) • Looked for relationship between mill frequency and population and relief • In the field, we looked for sediment deposits behind former mill sites and other evidence of landscape change

  5. Sample Town – Woodford, 1856 Population: 423 Mills: 20 saw mills (orange) 4 ocher mills and 1 oil mill (pink) Area: 123.28 sq. km Mill Frequency: .2028 mills/sq. km (highest of towns sampled)

  6. Results -predominantly saw mills -mill frequency Bennington 0.03 /sq km Caledonia 0.03 /sq km Chittenden 0.02 /sq km

  7. Results Burlington Woodford -slight inverse relationship

  8. Affect On Stream Path Upon Removal Of Dams 1857 Jericho 1996

  9. Conclusions • Higher mill frequency was found in mountains with higher average slope and less population density. • Sediment trapped behind dam was likely transported downstream after the destruction of the dam. • Change in Browns River displays the impact humans have on landscape change as far as the construction and destruction of dams

  10. Old Red Mill, Jericho Circa 1895 Yesterday
