Amygdaloid Island is separated by Amygdaloid Channel from Isle Royale. It had relatively low visitation until the 1990s, when the growth of
sea kayakingmade it possible for human-powered visitors to approach the island. The waters of Lake Superior around Amygdaloid Island are notoriously dangerous, however, and inexperienced kayakers are not encouraged to navigate them.
The island is the site of the "Amygdaloid Island Flow", a deposit of basaltic lava with silica inclusions. After the lava cooled, the inclusions hardened into pink agate specimens. The agates of Amygdaloid Island are characteristically almond-shaped or
amygdaloidal, hence the name "Amygdaloid".
On December 7, 1927,
lake freighter" SS Kamloops", operated by Canada Steamship Lines, was upbound with a crew of 22 seamen and a valuable cargo of papermaking machinery consigned to Thunder Bay, Ontario, when it sank during a severe snowstorm and gale on Lake Superior.
The following spring, the remains of several of the seamen who had been aboard the "Kamloops" on its final voyage were found at a campfire site on Amygdaloid Island. They had evidently died of starvation and exposure. Moreover, there was visual evidence that
wolveshad scavenged the victims' remains.
A popular local
ghost mythrecounts that crewmembers of the "Kamloops" walk Amygdaloid Island, looking desperately for food.
