Narrative:
Working sector 15 (sfc to FL280); when I took a hand-off on a single engine at 110 - publication..tcc..maf. The area in which the aircraft came over has a very high minimum IFR altitude (mia) in my airspace ranging from 102 to 116. The area in which the 116 mia is very small in my airspace; but it extends into ZDV sector 41's airspace according to my map. Shortly after I took the hand off from ZDV41 the MSAW went off showing that the single engine at 110 was below the mia. After I looked at our map; the aircraft would enter a lower mia within a couple of miles so I did not climb the aircraft above the mia. Similar to the southern portion of this airspace; I believe ZDV must have a lower mia than we do at ZAB; but I am not sure; and did not have time to ask. Shouldn't the mias along each facility's borders match up?
