I've been traveling in Denmark this past week, visiting family, an environmental artist, contemporary art and ancient artifacts. Starting with the oldest, yesterday I came to the largest boulder in Denmark, an erratic deposited on the land at the end of the last ice age. The monolith rests serenely in the midst of green, rolling farm fields, no other evidence of stone anywhere to be seen. It's estimated to weigh 1,000 tons and is 150' in circumference. "Hesselagerstenen" is in the town of Hesselager on the island of Fyn, central Denmark. The curiosity is a favorite among those of a geological bent, and climbing children.
