Our desire to study cryptomaria through analysis of dark-halo craters has prompted an experimental program to refine our understanding of the conditions of their formation. To this end, a series of impacts into layered sand targets was performed to determine mare (d(m)) and highland substrate (d(h)) penetration required to form or obscure a dark halo. Analysis of the results yields the relations d(m) = 0.21 d(e) and d(h) = 0.34 d(e) where d(e) is the depth of excavation. Caution must be used in applying these values, since our target materials do not simulate the spectral characteristics of the moon.
