Yup.  Air density drops with increasing elevation above sea level.  That reduced drag on the bullet and it retains more speed giving a flatter trajectory.  Shots will go high unless you compensate.  

There are changes in barometric pressure day to day (at the same location) that can affect trajectory too, but these are small and not noticeable out to around 600 yds.  At 1000 yds, you will notice slight changes.
