He I 10830 profiles acquired with Keck's NIRSPEC for 6 young low mass starswith high disk accretion rates (AS 353A, DG Tau, DL Tau, DR Tau, HL Tau and SVS13) provide new insight into accretion-driven winds. In 4 stars the profileshave the signature of resonance scattering, and possess a deep and broadblueshifted absorption that penetrates more than 50% into the 1 microncontinuum over a continuous range of velocities from near the stellar restvelocity to the terminal velocity of the wind, unlike inner wind signaturesseen in other spectral features. This deep and broad absorption provides thefirst observational tracer of the acceleration region of the inner wind andsuggests that this acceleration region is situated such that it occults asignificant portion of the stellar disk. The remaining 2 stars also have blueabsorption extending below the continuum although here the profiles aredominated by emission, requiring an additional source of helium excitationbeyond resonant scattering. This is likely the same process that produces theemission profiles seen at He I 5876
