Welcome to the technical sessions schedule for the 2015 Annual Fall NEARC Conference. 

NEW THIS YEAR!
 The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 9) or track (i.e. USGS Hydro). You can also search for a presentation title (i.e. Harmonizing the NHD and WBD Datasets in Maine), key term (i.e. NHD), or presenter last name (i.e. O’Neil-Dunne). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference. Click the "Sign Up" button in the top right corner of this page to create a Sched.org account.

Lidar can provide a whole new window into the landscape and can reveal previously unnoticed clues to surficial geologic features. It has proved invaluable in discerning locations of ancient shorelines. The current configuration of Lake Champlain has undergone many transformations in the past 13,000 years. As glaciers receded and the land surface was depressed, salt water invaded the Champlain Valley for a period of time - from what is now the St Lawrence River. Archeologists in search of evidence of Paleo-Indian habitation are focused on investigating areas near to the ancient shoreline of the Champlain Sea. Early native people inhabited landforms adjacent to the edge of this ancient sea and it was certainly a travel corridor. By integrating data from a wide variety of sources, the location of the shoreline can be determined with greater accuracy. Information on delta elevations, surficial deposits, archeological evidence and soils data are being combined to better define the location of the Champlain Sea. There are many benefits to this work including preservation of archeological sites and insights into current water quality issues that plague Vermont’s largest lake.
