Update on the analysis of near horizontal muons with HAWC

In this talk, I will present an update on the observation of near horizontal muons with the High Altitude Water Cherenkov (HAWC) gamma and cosmic ray observatory. The observatory is located at an altitude of 4100 meters a.s.l. on the Sierra Negra volcano in Mexico. The HAWC detector is composed of 300 large water tanks which are 7.3 m in diameter and 4.5 m tall and positioned over an an area of approximately 22,000 square feet. The positioning and height of the water tanks allows for HAWC to act as a Hodoscope for muons with trajectories very near 90 degrees zenith. This presentation will provide an update on work to obtain the rate of near horizontal muons corresponding to a minimum energy needed to penetrate the rock depth from Pico de Orizaba or Seirra Negra.
