Paul,

CityData[{All, "<state>"}] is not.  You need to also specify the country 
when using All.

CityData[{All, #, "UnitedStates"}]& /@ {...}


This works:

ListPlot3D[{CityData[#, "Longitude"], CityData[#, "Latitude"],
     CityData[#, "Elevation"]} & /@ CityData[{All, "Colorado", 
"UnitedStates"}],
  ColorFunction -> "Topographic", MeshFunctions -> {#3 &}]
