Maimekden (or May Mekden) is a village in Tigray Region, located 27 kilometers south of Wukro. It is located on the crossing of Ethiopian Highway 2 and the Mai Mekden river, flowing west to the Geba River.

Administrative division

In Imperial times, Maimekden used to be the administrative center of the Wenberta woreda, part of the Enderta province. Nowadays, the new Wemberta district has its center in the town of Atsbi and Maimekden is located in the Kilte Awulaelo district with Wukro as its administrative center.

Geology and soils

The following geological formations are present in this locality:[1]

Agula Shale[2]
Mekelle Dolerite[3]
Antalo Limestone
Quaternary alluvium and freshwater tufa, including a remarkable tufa dam west of the town[4]

The main geomorphic units, with corresponding soil types are:[5]

Gently rolling Antalo Limestone plateau, holding cliffs and valley bottoms on limestone
- Associated soil types
  - shallow stony soils with a dark surface horizon overlying calcaric material (Calcaric Leptosol)
  - moderately deep dark stony clays with good natural fertility (Vertic Cambisol)
  - deep, dark cracking clays on calcaric material (Calcaric Vertisol, Calcic Vertisol)
- Inclusions
  - Rock outcrops and very shallow soils (Lithic Leptosol)
  - Shallow very stony loamy soil on limestone (Skeletic Calcaric Cambisol)
  - Deep dark cracking clays with very good natural fertility, waterlogged during the wet season (Chromic Vertisol, Pellic Vertisol)
  - Brown to dark sands and silt loams on alluvium (Vertic Fluvisol, Eutric Fluvisol, Haplic Fluvisol)
Alluvial plain induced by tufa dam
- Dominant soil type: deep dark cracking clays with very good natural fertility, waterlogged during the wet season (Chromic Vertisol, Pellic Vertisol)
- Associated soil type: stony, dark cracking clays with good natural fertility (Vertic Cambisol)
- Inclusions
  - shallow, stony, dark, loamy soils on calcaric material (Rendzic Leptosol)
  - shallow, very stony, silt loamy to loamy soils (Skeletic Cambisol, Leptic Cambisol, Skeletic Regosol)

Roads

In May Mekden, the deviation of the regional highway which passes by Mekelle joins the National Highway 2 again continuing to the north towards Wukro, Freweyni, Idaga Hamus and Adigrat.

gollark: An extra script file could already interface with the existing stuff as far as I can tell.

gollark: Also, you can do the user mode thing *anyway*.

gollark: Simply use `eval`. This is very secure.

gollark: If you just split it into multiple files, that does basically nothing for the important things, the interdependencies between each part.

gollark: Organization is not autonomously attained via file restructuring.
