Yellow Diamond is mostly decomposed granite soil, which drains fast and firms up quickly after rain. That is a big part of why the live mud reading reacts the way it does after rain, and why some nearby trails dry out faster than others.
Yellow Diamond tops out around 433 ft. Higher Massachusetts trails hold snow later into spring, so this page tracks snow coverage and the estimated melt-out alongside the dry-dirt read. Check the current reading and the 10-day outlook before you head up. See the 10-day outlook →
