A fisherman tries his luck during low tide near Beards Hollow.

The peak low tides occurred Friday, July 23 with a -1. negative tide at 6:54 a.m. followed by a -1.7 minus tide Saturday morning.

Footprints in the sand revealed that the cave at Waikiki Beach at Cape Disappointment State Park was among the most popular early-morning destinations for curious explorers, many equipped with cameras and cell phones to document the dramatic changes sea-level changes have on the coast. Others found their way to Beards Hollow, where they discovered tide pools teeming with life, including crabs, sea stars, anemones and mussels.

The spectacle only lasted about two hours, as the tide change began to re-cover what had been revealed by the retreating waves.

The next series of significant minus tides will occur Saturday, Aug. 21 (-1.4, 6:38 a.m.) and Sunday, Aug. 22 (-1.4, 7:20 a.m.). There are -1.2 tides on either sides of those dates.
