Using infrared to (sub)millimeter data from Spitzer, Herschel, the James Clerk Maxwell Telescope, and the IRAM 30 m telescope, we conducted an unbiased survey of the massive dense cores (MDCs) in the Cygnus X molecular cloud complex, aimed at characterizing the physical conditions of high-mass star formation (HMSF) at ∼0.1 pc scales. We created 5° × 6° images of the 70–1200 μm dust continuum, gas column density, and dust temperature of Cygnus X. A spatial relation between the dense regions (A v ≥ 15) and the developed H
