  We present a framework for calculating the surface density profile of a stain
deposited by a drop with a receding contact line. Unlike a pinned drop, a
receding drop pushes fluid towards its interior, continuously deposits mass
across its substrate as it evaporates, and does not produce the usual "coffee
ring." For a thin, circular drop with a constant evaporation rate, we find the
surface density of the stain goes as $\eta(r) \propto
\left(\left(r/a_0\right)^{-1/2}-r/a_0\right)$, where $r$ is the radius from the
drop center and $a_0$ is the initial outer radius. Under these conditions, the
deposited stain has a mountain-like morphology. Our framework can easily be
extended to investigate new stain morphologies left by drying drops.
