The party now left the Barrier Range, and followed a course to another range further north, staying for some time at a small lagoon while engaged in making an examination of the country ahead. On the 27th of January, 1845, they camped on a creek rising in a small range, and affording, at its head, a fine supply of permanent water. When upon its banks the explorers pitched their tents, they little thought that it would be the 17th of the following July before they would strike camp again. This was the Depot Glen, and an extract from Sturt's journal depicts the situation of the party:-- "It was not, however, until after we had run down every creek in the neighbourhood, and had traversed the country in every direction, that the truth flashed across my mind, and it became evident to me that we were locked up in the desolate and heated region into which we had penetrated, as effectually as if we had wintered at the Pole. It was long, indeed, ere I could bring myself to believe that so great a misfortune had overtaken us, but so it was. Providence had, in its all wise purposes, guided us to the only spot in that wide-spread desert where our wants could have been permanently supplied, but had there stayed our further progress into a region that almost appears to be forbidden ground." This then was Sturt's prison -- a small creek marked by a line of gum trees, issuing from a glen in a low range. By a kindly freak of nature, enough water had been confined in this glen to provide a permanent supply for the exploring party and their animals, during the long term of their detention. Of Sturt's existence and occupation during this dreary period little can be said. He tried to find an avenue of escape in every direction, until convinced of the futility of the attempt; sometimes encouraged and lured on by the shallow pools in some fragmentary creek, at others, seeing nothing before him but hopeless aridity. Now, too, he found himself attacked with what he then thought to be rheumatism, but which proved to be scurvy. Poole and Browne were afflicted in the same manner. Sturt made one desperate attempt to the north during his imprisonment in the Depot Glen, and succeeded in reaching a point one mile beyond the 28th parallel, but further north he could not advance, nor did he find any inducement to risk the safety of his party.
