We present millimeter and submillimeter wavelength observations andnear-infrared K-band imaging toward the bright gamma-ray burst GRB 010222. Overseven epochs the flux density of the source was constant with an average fluxdensity 3.74+/-0.53 mJy at 350 GHz and 1.05+/-0.22 mJy at 250 GHz, giving aspectral index alpha=3.78+/-0.25. We rule out the possibility that thisemission originated from the burst or its afterglow and we conclude that it isdue to a dusty, high redshift starburst galaxy (SMM J14522+4301). We argue thatthe host galaxy of GRB 010222 is the most plausible counterpart of SMMJ14522+4301, based in part on the centimeter detection of the host at theexpected level. The optical/NIR properties of the host galaxy of GRB 010222suggest that it is a blue, sub-L_*, similar to other GRB host galaxies. Thiscontrasts with the enormous far-infrared luminosity of this galaxy based on oursubmillimeter detection (L_Bol~4X10^{12} L_odot). We suggest that this GRB hostgalaxy has a very high star formation rate, SFR 600 M_\odot/yr, most of whichis unseen at optical wavelengths.Comment: ApJ, submitte
