GL 2136 (1950:18h 19m 39.3s -13(o) 31' 18") and Orion BN (1950: 5h 32m 46s -5 (o) 24' 30") are classified as BN type objects which are characterized as infrared sources with color temperatures of 400 to 600 K and a nearly blackbody infrared spectral energy distribution. The spectral energy distributions of both objects have several absorption features at near infrared wavelengths due to different species of grains and ices including a prominent water ice absorption feature at 3.08 mu m. A comparison of the structural features of these two star formation regions is of scientific interest since the Orion BN-KL region is a cluster formation region and GL 2136 appears to contain a single massive protostellar object, IRS 1. The work presented here is part of a larger project that studies the two regions at several near-infrared wavelengths, using narrowband infrared imaging. The project focuses on the spatial distribution of compositional features and the possible affect of molecular composition on star formation rates. Presented are the 2.2 mu m (K-band), 3.08 mu m,( H_20 ice) and 3.45 mu m (narrowband L), 2.12 mu m (H_2 S(1) 1-0), and 2 .25 mu m (H_2 S(1) 2-1) images and analysis.
