A hole ran horizontally into the rock, and there was clearly something metal within it. Jake turned and beckoned, moving away from the pillar to allow Mikael access with his catch bag of extra gear. Mikael's scuba diving contacts had recommended bringing down a special type of pump which super-heated water and used a nozzle to direct the flow, causing the solidified salt to melt under the high pressure. Now Mikael took it from his bag and, bracing himself against the next pillar, he directed the nozzle towards the metallic glint.
The salt dissolved and swirled in the water like milk.
After another minute, Mikael shut off the flow and they waited a second for the cloudy water to dissipate before finning back to look at the pillar. The shape of a small metal box could clearly be seen.
