Abstract New J=1-0 HCO+ and J=2-1 C18O observations of HH24–26 reveal striking differences between these and previous maps of higher-J transitions of HCO+ and CS. The high-J HCO+ and CS emission traces the densest portions of the cloud, while C18O traces the more tenuous envelope. This is also evident in the velocity structure. HCO+ and C18O appear to be depleted from the gas phase by amounts which vary with position.
