Yerkes 1 is characterized by the presence of rilles in the summit. It has a height of 110 ± 20 m, a flank slope of 1.36° ± 0.20°, and a volume of 4.8 km3. Ye1, with its low flank slope and rather low edifice volume, belongs to class B2. If the effusion of lava continues over a long period of time, a steep flank slope and high edifice volume may occur as in the case of class B1 domes (as for the dome Piccolomini 1), while short durations of the effusion process result in lower and less voluminous edifices, as it is the case for domes of class B2 such as Ye1.
