AB  - This paper updates the record of atmospheric dust loading within northern Gale 
      Crater, Mars, by providing line-of-sight extinction (LOS-Ext) measurements of the 
      intervening dust between the rover and the crater rim. These measurements are 
      derived from images taken with the Navigation Cameras (Navcam) onboard the Mars 
      Science Laboratory (MSL) rover, Curiosity. The observations span 2.44 Mars years, 
      from Mars Year (MY) 31 at a solar longitude (L (S) ) of 208 degrees  to t L (S) = 7 degrees  of 
      MY34, sols 100 - 1701 of the MSL surface mission. This work examines the dataset 
      for seasonal trends of the LOS-Ext in addition to horizontal variations and the 
      vertical structure of LOS-Ext. The LOS-Ext has a repetitive pattern with a single 
      peak in the latter half of the Mars year. The atmosphere in the crater is well 
      mixed horizontally but not vertically as larger LOS-Ext is seen nearer the crater 
      floor than at higher altitudes within the crater. The results allow a discussion 
      on whether or not Gale Crater is a sink for atmospheric dust or a source of 
      atmospheric dust in the current era.
