“The Umbazookskus River is called ten miles long. Having poled up the narrowest part some three or four miles, the next opening in the sky was over Umbazookskus Lake, which we suddenly entered about eleven o'clock in the forenoon. It stretches northwesterly four or five miles, with what the Indian called the Caucomgomoc Mountain seen far beyond it. It was an agreeable change.”
“This lake was very shallow a long distance from the shore, and I saw stone heaps on the bottom, like those in the Assabet at home. The canoe ran into one. The Indian thought that they were made by an eel. Joe Aitteon in 1853 thought that they were made by chub. We crossed the southeast end of the lake to the carry into Mud Pond.”
—Henry David Thoreau, “1857 Allegash and East Branch”, The Maine Woods
