Truth to Nature: The Art and Ecology of Hudson River School Painting

Creator:: Loeb, Harper
Abstract:: Beginning with the inception of American art history as a formal discipline in the 1940s, the dominant mode of interpreting nineteenth-century American landscape painting has been to view aspects of the landscape as symbols for grand cultural, religious, national, and moral narratives. While this method of interpretation highlights some key...

Potential for Coastal Wetland Blue Carbon Offset Projects in the Point Reyes Area

Creator:: Minnick, Margaret T.
Abstract:: Point Reyes is a 100-square mile peninsula located on the California coast about 30 miles north of San Francisco. The peninsula, surrounding bays, and neighboring coastal mainland are a unique biodiversity hotspot. The area underwent heavy human use, including ranching and logging, during the late 1800s and early 1900s. Conservation...
