Broad and narrow band 1-4-micron and red CCD images of the star formation complex associated with the 'cometary' nebula GM 24 are presented together with a medium-resolution 2.16-micron spectrum of the most conspicuous source. A young IR cluster of more than 23 stars is embedded in the densest and hottest parts of the dense molecular cloud. Most of the embedded stellar objects show large infrared excesses at lambda equal to or greater than 2.2 microns. The obscuration toward the center of the cluster (Irs3) is found to be AV = 55. A compact 'blister' H II region is associated with Irs3.
