Shell Spring, Biscuit Basin, Yellowstone National Park, Wyoming, August 6, 2010 (Pentax K10D)

Shell Spring’s name is derived from the shape of the it’s crater, a geyserite structure vaguely reminiscent of a giant clam shell. It is a cyclic geyser with several hours of recovery between the long lasting active phases.  Although the spring is only 2 feet deep, in 1930 a 3-year-old Idaho girl fell into it and, later, died from her injuries.¹

Temperature 200°F Interval 1.5 to several hours. Duration 20-90 seconds. Height 5-8 feet. “Before an eruption, water in the crater begins to rise and may boil. Heavy churning then occurs, setting off the first small, weak eruption. As the eruptions subside water begins to lower and drain back into the crater.” ²

Split Rock Lighthouse, Split Rock Lighthouse State Park, near Silver Bay, Minnesota, June 12, 2018.

Split Rock Light Light²

Split Rock Lighthouse is a lighthouse located southwest of Silver Bay, Minnesota, USA on the North Shore of Lake Superior. The structure was designed by lighthouse engineer Ralph Russell Tinkham and was completed in 1910 by the United States Lighthouse Service at a cost of $75,000, including the buildings and the land. It is considered one of the most picturesque lighthouses in the United States.

Split Rock Lighthouse was built in response to the great loss of ships during the famous Mataafa Storm of 1905, in which 29 ships were lost on Lake Superior. One of these shipwrecks, the Madeira, is located just north of the lighthouse.

It is built on a 133-foot (41 m) sheer cliff eroded by wave action from a diabase sill containing inclusions of anorthosite. The octagonal building is a steel-framed brick structure with concrete trim on a concrete foundation set into the rock of the cliff. It is topped with a large, steel lantern which features a third order, bi-valve type Fresnel lens manufactured by Barbier, Bernard and Turenne Company in Paris, France. The tower was built for a second order lens, but when construction went over budget, there was only enough funding remaining for the smaller third order lens. The lens floats on a bearing surface of liquid mercury which allows near frictionless operation. The lens is rotated by an elaborate clockwork mechanism that is powered by weights running down the center of the tower which are then reset by cranking them back to the top. When completed, the lighthouse was lit with an incandescent oil vapor lamp that burned kerosene.

At the time of its construction, there were no roads to the area and all building materials and supplies arrived by water and lifted to the top of the cliff by crane. The light was first lit on July 31, 1910. Thanks to its dramatic location, the lighthouse soon became a tourist attraction for sailors and excursion boats. So much so, that in 1924 a road (now Minnesota State Highway 61) was built to allow land access.
