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 Cand 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.
