- Description:
- This intact boiler, one of the two preserved examples, provided the necessary steam required to operate the press engine and other processing equipment. The holes on the end plates suggest that the steam was supplied by a system of horizontal return tubular (HRT) fire tube boilers. Each opening was connected by a horizontal tube to its counterpart on the opposite end. Heat was conducted from the externally-fired dutch oven through each tube via a flue on the back end of the combustion chamber. The multiple tubes created a large surface area for heating the surrounding water within the sealed boiler. At least 114 openings can be counted on one intact boiler end. Deerr (1911:404) calculated that a seven foot diameter boiler with 120 tubes can supply 1800 ft² of heating surface.

42. Water Cisterns
- Description:
- A large in-ground water retention basin background), measuring approximately 16x9 m and constructed of thick volcanic rock and marine sand mortar walls over 1 m wide and 2 to 3 m high, dominates the northern end of the mill area. An opening at the bottom of the deepest corner of the basin transferred water into a smaller and deeper adjoining water reservoir (foreground) with a metal tube drain imbedded in its west wall. The smaller reservoir is located close to the stone wall with a tunneled flue connected to the smokestack.

- Description:
- The first known introduction of goats to the islands may have occurred as early as AD 1693. Currently naturalized on three islands and eradicated on another 11, goats are a highly problematic invasive. These feral goats were photographed in 2014 in the highlands above Hacienda La Tranquila, despite declarations that no wild goats were to be found on San Cristóbal.

- Description:
- The artifact-rich lense of the Carpintero midden can be seen as its surface is exposed during excavation in 2014. Filled with discarded animal bones, glass bottles, and ceramics, artifact deposition was so dense, that recovered materials often exceeded the amount of associated soil by volume.
