Sarah Crump Graduate Fellowship 

Sarah Crump, in purple coat, stands in front of a dramatic Baffin Island landscape of colorful tundra suddenly broken by towering cliffs.

Next application deadline: Late February, 2026.

Thanks to the efforts of Sarah's family and 1200+ generous donors, we met our first funding goal in May 2023 and created an endowment that supports a CU Boulder grad student every summer. Sarah's summer fellowship gives a boost to their study of Earth or environmental science in Arctic, Antarctic, or alpine regions. It also acts as a lever for equity and underserved communities. Our next goal is to extend summer support into the school year. Please consider contributing.
