Project Protocols

Exhibit & Picnic Registration

Document Spring brings together expert nature photographer Dudley Edmondson and area students to capture the emergence of spring from Oldenburg House to Oldenburg Point in Jay Cooke State Park.

Beginning April 26 and continuing through June 1, students will safari with Dudley to selected locations to capture images and record seasonal changes, creating an annual record of spring’s arrival in our community.

Images of spring will be shared on the Document Spring website and exhibited at the Document Spring Celebration at Oldenburg Point in Jay Cooke State Park on Saturday June 2, beginning at 11am.


Dudley Edmondson

Dudley Edmondson is the author of the landmark book, “Black & Brown Faces in America’s Wild Places,” profiling African Americans in nontraditional vocations and avocations in the outdoors.

Mr. Edmondson speaks regularly on his books and his career as a Wildlife Photographer. Dudley’s photography career spans nearly 3 decades. His work has been featured in galleries and in nearly 100 publications around the world.

Dudley is a lifelong nature advocate and is passionate about bringing diverse voices into the conservation conversation.


Phenology is the study of seasonal plant and animal cycles and how variations in climate, habitat factors affect the emergence of leaves and flowers, the first flight of butterflies, and the first appearance of migratory birds.

Document Spring combines the artistry of photography with the systematic gathering of scientific data. OACC engaged these experts to develop the Phenology Protocol for Document Spring. We are immensely grateful for their expertise and their enthusiasm for Document Spring as a citizen science project.

Historical Context

Oldenburg Arts and Cultural Community is honored to partner with Jay Cooke State Park. Henry and Mary Oldenburglong championed the birth of Jay Cooke State Park and Oldenburg Point in the park celebrates their efforts. The Oldenburgs built their house adjacent to the Park in 1894 and held frequent gatherings of scholars, activists, and artists. Their daughter Margaret followed in her parents’ footsteps as a conservationist and anthropologist. Document Spring carries this tradition forward.
