'The Lake Powell Assembly' provides a means to gather and collect sediment data in Lake Powell, California, through a series of seasonally flooded camping spaces for travelling and explorers. The assembly has been set up to investigate the excessive saturation of the lake with sediment, a condition which has been caused by the construction and operation of the Glen Canyon Dam.

Inspired by the construction of oil rigs and submarines, the architecture becomes an instrument that collects sediment and records the environmental changes that are caused by the dam. The architecture also traps sediment, both locally on site and downstream, in order to redistribute it to the diminishing Grand Canyon beaches. These are important for their provision of temporary habitation for explorers and permanent habitats for native fish life.

A key attribute of the architecture is the framing of the Moon, and in particular the full Moon, which is used for triggering an emotional response in the building's visitors, heightening their specific experience of the environmental conditions of the site. The Moon has a historical relationship with Lake Powell, and was used to magnify poetically the experience of the river's canyons by artists who visited and recorded the region.
