The spring box is also lined with tufa. It resembles a veneer of creamy brown butter spread on every surface. Tufa is a soft porous type of limestone produced when calcium carbonate precipitates out of water that has surfaced from deep aquifers rich in lime like those around Pogonip and campus. The tufa even precipitates on twigs and leaves. In some cases, tufa has enveloped twigs that later decompose and leave tiny craters and tunnels within the tufa.
