Normally, Fisher explained, the university wouldn't have put resources into excavating remains without some reassurance that they'd be donated for research.
"When they finish with the wood, they will throw themselves into excavating the ruins, because that will be all that is left for them to destroy," said William Perlas Pineda, El Ceibal's caretaker.
Each lateral twenty-foot segment of excavation required the insertion of slurry walls and a system of horizontal struts to support them so that the surrounding earth, and therefore the sidewalks and buildings, wouldn't collapse into the excavated pits.
Sometimes the forms multiply like cells, as in "Disperse" (2010), composed of dozens upon dozens of blown glass circles that look like bubbles on the surface of water, and sometimes they're carved into and excavated, as in "Vestige" (2004), an ephemeral cut-paper piece embedded in the wall.
Another variation, when the aquifer is too far below the surface for the basin system, is to discharge the water into shafts or wells excavated into the aquifer.
The trails are sometimes carved into the mountain, turning into narrow trenches excavated by water and decades of transit.
Associations between fungi and endangered red-cockaded woodpeckers (RCWs) are particularly interesting because these are the only birds that specialize in excavating into the heartwood of living pines, a process that takes years to complete.
Tut's tomb will be transformed into the recently excavated temple of Venymyss and the space converted into a queue for the new ride.
Field observations indicate that current engineering practice does not consistently estimate ground water flows into unlined rock excavated tunnels due to various factors that analytical solutions do not take into account.
Tomb chapels were excavated into the rock of the cliffs overlooking the Nile.
