The HAWC Observatory in Sierra Negra, Mexico has recently recorded its trillionth cosmic-ray air shower in just over 1 year of operation. Using this high statistics data set, we have studied the arrival direction distribution of ~1-100 TeV cosmic rays. The sub-degree angular resolution of the air shower reconstruction allows us to examine the known features of the Northern TeV cosmic-ray sky with unprecedented precision at large (>60°) and small angular scales. We will report the results of our analysis which is sensitive to ~10^-4 anisotropy. Measurements of anisotropy are being used to improve our understanding of the distribution of local cosmic-ray accelerators and orientation of local magnetic fields.
