From tidepooling to witnessing Oregon’s tallest lighthouse, there is something for every visitor at Yaquina Head. Yaquina Head Outstanding Natural Area extends out from the Oregon coast, one mile into the Pacific Ocean. Standing 93 feet tall at the westernmost point of the basalt headland, the lighthouse has been a bright beacon of the night, guiding ships and their supplies along the west coast since the light was first lit on August 20, 1873. In the tide pools, visitors can see marine life such as anemones, urchins, mussels,  barnacles and seastars. Photo by Bob Wick, Bureau of Land Management (@mypubliclands).

Astronomy Picture of the Day: October 02, 2018 Yes, but can your rainbow do this? After the remnants of Hurricane Florence passed over Jersey Shore, New Jersey, USA last month, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of rainbows. Over the course of a next half hour, to the delight of the photographer and his daughter, vibrant supernumerary rainbows faded in and out, with at least five captured in this featured single shot. Supernumerary rainbows only form when falling water droplets are all nearly the same size and typically less than a millimeter across. Then, sunlight will not only reflect from inside the raindrops, but interfere, a wave phenomenon similar to ripples on a pond when a stone is thrown in. In fact, supernumerary rainbows can only be explained with waves, and their noted existence in the early 1800s was considered early evidence of light’s wave nature.

Exit Glacier is the only part of Kenai Fjords National Park in Alaska accessible by road. From the Nature Center, visitors can explore trails, walk very close to an active glacier or take a ranger-led walk. It’s a place where you can witness up close how glaciers re-shape a landscape and learn how plant life reclaims the barren rocky land exposed by a glacier’s retreat. In the summer, the wildflower blooms and endless views make the experience magical. Photo by Catherine Danley (www.sharetheexperience.org).
