Scrub the ring. Using the toothbrush, gently scrub the ring, working the bristles into the nooks and crannies between the diamond and the setting. Rinse in warm water and leave to dry. Be certain to rinse all soap from your ring. Lay it on a piece of tissue to dry.
Hike #3, Pleasants Ridge hike: This hike goes up the east side of the canyon, up a steep slope through blue oak woodland and grassland. It offers great views of Cold canyon as you hike up, and terminates at a rock outcropping on the ridge. The ridge is spectacular, and is a real knife-edge. Great views of the Putah Creek wildlife area and the valley can be seen from here. Distance: 0.5 mile to the top of the ridge, with an elevation gain of 1040 feet.
Those canyons that are now submerged may have once held rivers and waterfalls that carved the canyon walls, carrying the sediment and debris down into shallower sea. The largest and deepest submarine canyon ever discovered is in the middle of the Bering Sea called the Zhemchug Canyon.
