Scientist Measuring Lichen on Granite Near Soroti

Bright midmorning light illuminates a patch of grey granite near Soroti, its surface wet and glistening from recent rain. A researcher stands in the frame, holding a white ruler card steady against the stone to measure a cluster of crustose lichen. The rock texture is rough and pitted, against the smooth plastic of the measurement tool. Cool season air leaves the granite surface damp, reflecting the sky in subtle, scattered highlights. The ruler's black markings are sharp and distinct against the pale card, providing a precise scale for the biological growth. Water droplets rest on the uneven stone edges, catching the soft light. The scientist's hand rests firmly on the card, ensuring the measurement remains level and accurate against the rugged terrain.
