Narrative:

After breaking out under the clouds on the RNAV GPS runway 34 at ciu during high winds and blowing snow partially obscuring the runway we both visually saw the runway pavement. Runway markings were poor and unfortunately we were unable to see the yellow chevrons depicting the relocated threshold. Both flight crew members thought that the runway began at the beginning of the paved surface. This being the case we touchdown short of the landing threshold by about 50 feet.root cause was in my opinion a poor job of depicting this runway/relocated threshold on the jeppesen 10-9 chart; we looked up the government chart for the same airport and it clearly depicts the large portion of the runway that is no longer used for landing from this direction. Blowing snow and low visibility; and poorly painted markings all added to the lack up perceptibility of this layout. Improvement of the jeppesen 10-9 chart and a writeup in company charts explaining the situation should another crew execute this approach in similar meteorological conditions.
