  As the first step of a multi-wavelength investigation into the relationship
between young stellar clusters and their environment we present fully-sampled
maps in the J=1--0 lines of 13CO and C18O and the J=2--1 line of C18O for a
selected group of thirty young stellar groups and clusters within 1kpc of the
Sun. This is the first systematic survey of these regions to date. The clusters
range in size from several stars to a few hundred stars. Thirty fields ranging
in size from 8'x 8' to 60'x 30' were mapped with 47'' resolution simultaneously
in the J=1-0 lines with Five College Radio Observatory. Seventeen sources were
mapped over fields ranging in size from 3'x 3' to 13'x 13' in the J=2--1 line
with 35'' resolution with the Heinrich Hertz Telescope. We compare the cloud
properties derived from each of the three tracers in order to better understand
systematic uncertainties in determing masses and linewidths. Cloud masses are
determined independently using the 13CO and C18O transitions, these masses
range from 30 to 4000 M_sun. Finally, we present a simple morphological
classification scheme which may serve as a rough indicator of cloud evolution.
