We obtained 350 and 850 micron continuum maps of the infrared dark cloudG049.40-00.01. Twenty-one dense clumps were identified within G049.40-00.01based on the 350 micron continuum map with an angular resolution of about 9.6".We present submillimeter continuum maps and report physical properties of theclumps. The masses of clumps range from 50 to 600 M_sun. About 70% of theclumps are associated with bright 24 micron emission sources, and they maycontain protostars. The most massive two clumps show extended, enhanced 4.5micron emission indicating vigorous star-forming activity. The clump size-massdistribution suggests that many of them are forming high mass stars.G049.40-00.01 contains numerous objects in various evolutionary stages of starformation, from pre-protostellar clumps to HII regions.
