grooves with low sun angle     grooves under cloudy conditions

Figure 2. Figure 2A and Figure 2B are close-ups showing identical parts of the same outcrop on Clarry Hill, taken on the same two days as Figures 1A and 1B. Here the contrast between sunlit and sunless views is even more striking. The glacial grooves seen here easily could have been overlooked on a cloudy day!
