In the complete ophiolite sequence found at Leka one can also experience to walk on MOHO (Mohorovicic discontinuity), the transition between the oceanic crust and the mantle. At northwest Leka there is a hiking trail leading up to MOHO, here seen as a border between dunite and harzburgite. The transition is gradual over 10-20 cm.
There is a resting place and an existing information sign at this site today. Other types of ultramafic rocks to be seen in the area are lherzolite and layers and dykes of websterite and orthopyroxenite.
