A newly-documented site to the north of Tikal illustrates the range of features uncovered by lidar, as well as the complexity of interpreting them. The elongated building at top right is part of a so-called E Group complex and may pre-date 500 BCE. Across the valley, the large acropolis is likely a thousand years younger, though it may cover earlier constructions. Its broad access ramp overlaps an earlier causeway that runs between two eroded hilltop platforms, at the top and bottom of the image. Small houses and sunken garden enclosures cover the hillsides.
