  We investigate the multi-valley energy landscape of a 3-D on-lattice network
model for covalent glasses, numerically determining the shape of the valleys,
the local density of states, the density of minima and the local connectivity.
We present some of these quantities in a graphical birds-eye view of the
landscape, and discuss their implications for the relaxation dynamics and
cooling behavior of glasses. The strong similarities between the landscape of
this model and those of other complex systems point to the possibility of a
common low-temperature dynamical description.
