although originally based in georgetown, the pair found the evenings to be too cloudy to make observations of the night sky due to georgetown being located downwind of orthographic cloud emanating from green mountain. isobel quickly endeavoured to find an area less affected by the evening cloud and trekked for several miles over lava fields to find a new location. having found an area on the south west of the island seemingly less affected, they then had to determine how to move 20 tons of delicate observational equipment to the new location. fortunately a small clear beach was located nearby which was used for landing the equipment by sea. this was later named mars bay, a name which it carries to this day and which has since been designated a nature reserve. the couple then spent several months camped out at the bay making their observations, assisted by a krooman and a marine.
