Newly enamored ofthe country since producing documentary "Albino United" --- about an albino football team in Tanzania -- in 2010, Broomfield is shooting his next feature film in the city of Mwanza on the shore ofLake Victoria in the north-west ofthe country.
An 1836 map ofthe city shows several large islands in the middle ofthe river, Michigan's longest running 232 miles from the center ofthe state west to Lake Michigan.
The team also hopes to take samples of mud from the bottom ofthelake, to better understand the geological history oftheWest Antarctic Ice Sheet and Earth's past climate.
