Elevation and Pebble Count Data for 5 New Sites in Glaciated Setting of Pennsylvania and Southern New York, 2016 Elevation and Pebble Count Data for 5 New Sites in Glaciated Setting of Pennsylvania and Southern New York, 2016

This dataset contains elevation and pebble count data for 5 new sites located at streamflow-gaging stations in the glaciated setting of Pennsylvania and southern New York. Sites were surveyed in 2016 and the elevation data represent topographic features (bankfull, thalweg, etc.) along longitudinal and cross sectional areas of stream reaches. The pebble counts were collected within each...
