How can we identify star forming cores? Original idea: hot core tracers + outflows. Does that work? CH$_3$OH masers, but incomplete/maybe just shock tracers?  Evolutionary sequence in massive cores seen in dust ridge clouds. Steve: free-fall times come from single-dish, large scale. Diederik: position along ridge dominates spread in density.  Lines mapped: H$_2$CO, C$^{18}$O, CH$_3$OH, $^{13}$CO, SiO.
