The heights of Wollaston 1-3 correspond to 50 m, 55 m
and 40 m, respectively, resulting in average flank slopes of 1.0°, 0.60° and 0.54°.
Based on
the inferred rheologic properties and morphometric properties the domes Wollaston
2 and 3 belong to the class C1, while the smaller dome Wollaston 1 belongs
to class C2 and E2. Wollaston 2 and 3 were formed from lava of viscosities of 103
Pa s over a period of time of about 0.3 and 0.15 years, respectively. The dome Wollaston
1 was formed from lava of viscosities of 104 Pa s over a period of
time determined to 0.3 years.
