Weathering pits are well known from granite terrains and they also form in metaquartzite along the Blue Ridge Parkway in North Carolina. We will drive to Flat Rock Trail, along the Blue Ridge Parkway near Linville, NC. After a short hike up the trail we will observe the weathering pits exposed on the bedrock surface overlooking the Linville Valley. Each group of students will write down 3 hypotheses for how and why they form. Consider what factors control the size and shape of the pits. Collect data that can be used to test the hypotheses including orientation, size, and shape. Plot the data collected in the field. Present data on graphs and charts. Do trends in the data support one hypothesis over another? Designed for a geomorphology course
