28th January 1933 cont. - we crossed mazes of plains and hillsWe were still south of the main part of the range, passing during the morning Mount Sonder, Glen Helen mountain, Mount Razorback, Mount Heulin and several other quite large peaks all within a few miles of one another and all in line. Then we crossed mazes of plains and hills some just sand with nothing growing at all and others well grassed with many trees. After about fifteen miles we had a great suprise as we came on a rock pool of beautifully clear fresh water. It not only provided drinking water but a swim, a drink for the camels, washing up water and a subject for Murch to paint. There we made a stay of about two and a half hours before again pushing on.
