Spring has sprung at Haystack Rock and with it volunteer and staff Environmental Interpreters are finding loads of eggs and tiny juvenile recruits of different types.

Interpreters, throughout the past two weeks, saw HIGHLY variable weather patterns, causing high wind, surf, and surge warnings. In the image below, check out the hail covering the beach at Haystack Rock (and awesome staff and visitors still out tide pooling in the crazy…
