In order to better understand the nature of equilibrium structures like the flared outer disk and hot stellar halo of the Large Magellanic Cloud (LMC), I have reexamined the content of the 2MASS database on lines of sight toward the periphery of the LMC. I find evidence for a metallicity gradient as a function of projected radius based on the dereddened colors of the LMC's red giant branch (RGB) stars. I also find that the projected center of the number density contours depends systematically on the selected color (metallicity) of the RGB stars. Implications for microlensing are discussed.
