The temperature, density and kinematics of the gas and dust surrounding theluminous young stellar object GL~2591 are investigated on scales as small as100 AU, probed by 4.7 micron absorption spectroscopy, to over 60,000 AU, probedby single-dish submillimeter spectroscopy. These two scales are connected byinterferometric 86-226 GHz images of size 60,000 AU and resolution 2000 AU incontinuum and molecular lines. The data are used to constrain the physicalstructure of the envelope and investigate the influence of the young star onits immediate surroundings.Comment: To be published in The Astrophysical Journal, Vol. 522 No. 2 (1999 Sep 10). 45 pages including 11 figure
