From the excavation report: "The double-banked monument known as the Knockans at Teltown, County Meath, was partly destroyed in May 1997. Excavation (on behalf of the National Monuments Service) was undertaken there in 1997 (Excavations 1997, 143), and a second season, of nine weeks' duration, took place in July and August 1998.
The focus of this excavation was the eastern side of the southern bank, in order to complete the recording of the archaeological layers exposed by machine in 1997. Excavation revealed that there was a much greater depth of deposit in the central organic core (the burnt deposit) of the monument than the 0.8m recorded in 1997. The core, buried beneath 1-2m of redeposited gley, was made up of layers of deposited silts with some large stones revetting their southern side. Over these, and on the northern side, were many lenticular deposits of silt with pointed stakes driven into them.
Because of machine destruction the relationship of the organic core to what appeared to be a ditch between the two banks was not resolved in 1997, the old ground surface not being clearly identified. Excavation of a greater depth of this organic core in 1998 clarified this issue and demonstrated that the banks were constructed without an intervening ditch, the gap between them containing a considerable depth of silts and clay resting on the original ground surface. Although it was not possible to complete the excavation of this year's cutting to sterile ground across its entire length, it was possible to recover secure samples for dating and analysis from undisturbed contexts.
The reinstatement and grass planting of the northern bank was completed, but the final reshaping of the upper eastern slope of the southern bank was not finished as additional topsoil was required; the reconstruction of this small area will now have to wait until dryer weather in spring 1999.
Finds consisted of post-medieval pottery and modern material from the plough zone at the southern end of the southern bank. Flint and a fragment of bronze were recovered in the lower layers of the bank construction material, while fragments of leather, wood, a small amount of bone and one sherd of glass came from contexts within the organic core.
