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 exquisite, ephemeral world of spring-breeding amphibians.

1 to 3 p.m. at the Horatio Colony Nature Preserve, off Daniels Hill Road in Keene. Space is limited, and registration is required.
