Over the past few years, the British Museum has continued to expand their online offerings. In their "Explore" area, they have created a number of online tours that explore Asia, Africa, ancient Greece, Egypt, and Japan. This particular online tour covers the Americas through a number of thematic collections culled from their vast holdings. Visitors might wish to start by looking over the tour that includes images of kayak clothing from Greenland, as it provides some nice images and a number of insights into how kayakers past and present cope with the bone-chilling cold of the Arctic region. Moving on, the site also includes a tour titled "Unknown Amazon". Here, visitors can learn about the people who have inhabited the Amazon River basin over the past several thousand years.
