steck (plural stecks) (Scotland, Northern England, obsolete) A piece or an item.
So technically I guess this multicache is a Triple Steck.... 3 pieces
At Stages 1 and 2 you will find tubes thru which you can read the coordinates of the next stage. At Stage 3 you will find a small container with a log and a little room for tradeables.
Be alert for typical desert flora and fauna. Enjoy the hike.
Congratulations to PeachBob for the FTF!
