Mussel Creek   9/9/16
May reach the ocean at high tide; otherwise, meanders with low water

Sep 9, 2016 11:45 AM
Beautiful day on beautiful beach. Today's temperature was 79 when we started and 84 when we finished. In August, 2015, one year ago, the temperature was 63 -- nearly 20 degrees cooler. To the non-believers: climate change is real and active! Sandy beaches more abundant this time of year; next quarter will be different.   MORE

The mile could not be accessed from Arizona Beach -- Mussel Creek was impassable; the southern access from Frankport site was flooded, we parked in the area south of that. Because of high seas with big surges, only a small portion of the south end of the mile could be accessed. "Every picture tells a story, don't it?"   MORE

Mussel Creek channel is meandering, narrower and deepening. This mile remains relatively free of human/marine-caused debris. The new signage at the Arizona Beach end and Sisters Rocks end makes clear what is permissible and what is not. Unfortunately, the sign at the Sisters Rocks is behind the access gate, so vehicles can continue to enter and claim "oblivion" to the sign -- "just didn't notice" -- prohibiting vehicle entry.   MORE

Starting in dense fog, and returning with the skies lifting. Mussel Creek, requiring crossing in SOLV bags, is full and flows due north into mile 41. Another intriguing trek, especially since the usually impassable-by-shore area on the south end of the mile, close the Frankport site area, presented a wide, flat expanse of beach -- at least 100' to water two hours past low tide -- a much easier way to go! The previously reported domestic goat foursome has been reduced to three. One remains collared with a brass tag. They appeared scruffy, curious, but cautious; munching seaweed on the rocks. There was what appeared to be a grave -- missing goat? -- in the area we first spotted them.   MORE

An abandoned fire took our time and attention on the south end of the mile (north from Sisters Rocks). Due to winter storms, we were unable to cross the hugely expanded Mussel Creek at the Arizona Beach end of the mile. Mussel Creek now travels a long distance north before making an abrupt turn to the sea. This report will be augmented by a further report when we are able to return and cross Mussel Creek to complete the mile, north to south.   MORE

Mussel Creek now opens directly west -- wading to cross required. Seasonal sand removal makes this a "bouldering" mile -- difficult to walk it. Very little evidence of marine or human debris except for broken bottles on rocky beach below Frankport site entrance. Contrary to "What happens on the Mile stays on the Mile," if you bring bottles in, pack them out! Another lovely day at the beach . . .   MORE

The outlet of Mussel Creek has significantly moved to the south. The portion of Mussel Ck. that traverses the sand has created a dividing line between the west side wave-swept beach where there is no vegetation, and the higher elevation east side beach which now has plentiful vegetation. Of note are beach morning glory, searocket, yellow sand verbena, lupine, seaside plaintain, beach silverweed, cat's ear, angelica, coyote bush, and bird's-foot trefoil.   MORE

Another terrific adventure along this wild mile. Spring flowers including iris, strawberry, aster, wild cucumber. We had to complete the mile from two access points because low tide still did not permit access around one point. Marine debris abounds. Challenge other mile tenders to always carry a bag or 2 or 4; so when beach strolling folks offer their thanks for what you're doing, you can produce a bag and . . . We're delivering our bags of marine debris (NO household garbage) to Art 101 just south of Bandon for the traveling Washed Ashore project. Angela Pozzi welcomes these deliveries. (She cannot take debris scaled with decaying animal shells, carcasses, etc.) Let's clean these Pacific Coast beaches, and engage others globally!   MORE

Bicycle, road sign, tires, glass, plastic, styrofoam, tin - the only sign of humans was what they left behind. Garbage and debris, both discarded and drifted in from offshore activities, is very damaging and offensive to this beautifully wild and pristine area. However, where the beach travel was difficult, and humans did not further venture, the wildlife is natural and rewarding. Erosion in the area, above and down into the foredune, is very evident and somewhat extreme. Perhaps significant, the anchored staircase was not there -- removed for the season, or just gone? But wait. There is great news! The Brown Pelican juvenile, rehabbed at Free Flight Bird Rehabilitation for several months, and released by us at Arizona Beach in August '09, apparently went south with the flock!! Happy New Year!   MORE
