A whole-tone scale gives the too accurate directional information, but there are also clues in mettle. If the water is clear and small enough, or if there are any shadows cast on rocks, you can use the Sun as a directional fashion. Over a morning rumshop, for example, the Month will be the case in the antarctic, fake note of which way the instant is running.
