Nature Notes: Glacial Relics
While driving up the California coast on U.S. Route 1, particularly so from Morrow Bay on up to Monterey, Julie and I spotted several large coastal boulders, some white, some dark, some with birds, a few with sea lions, but almost all pyramid-shaped. We suspect that at least some of the whiteness was attributed to uric acid depositions from birds, or guano, as many of those white rocks had cormorants perched on them.
