This sea arch was a well-known feature along the
Lake Superior's North Shore. Sometime during the
week before August 22, 2010, the arch collapsed,
leaving a lone un-supported stack in its place.
The arch was located in Minnesota's Tettegouche State Park
about 62 miles north of Duluth on Route 61.
One might assume that the collapse of an arch
would be a fairly rare occasion. However, during
the few years the author has maintained this website,
he has been apprised of the fall of several, including
Sally's Arch (along Potash Mine Rd near Moab),
Aardvark Arch (along the west bank of the Great
Salt Lake), Wall Arch (in Devil's Garden, Arches N.P.),
and Ephemeral (in Valley of Fire State Park in Nevada).
Of the above, the delicate nature of Ephemeral
made it a prospective candidate for collapse; while the
others appeared to be pretty solidly constructed.
