Glance at a vernal pool in October, and you’ll see a dry depression in the forest floor. Look again in April and you’ll find a woodland pond, alive with amphibian eggs. Join Harris Center ecologist Brett Amy Thelen for a moderately strenuous, 1.2-mile roundtrip hike to a hilltop vernal pool, where we’ll explore the ephemeral world of spring-breeding amphibians.

1 to 3 p.m at the Horatio Colony Nature Preserve in Keene. Space is limited, and registration is required. For general information about Harris Center field trips, including questions about accessibility, see our Outings Information page. For questions about this particular outing, contact Brett.

Cosponsored by the Harris Center for Conservation Education and the Horatio Colony Nature Preserve.
