The Journal of Gregory Blaxland 1813

On Wednesday, the 19th, the party moved forward along this path; bearing chiefly west, and west-south-east. They now began to ascend the second ridge [Note 18] of the mountains, and from this elevation they obtained for the first time an extensive view of the settlements below. Mount Banks bore north-west; Grose Head, north-east; Prospect Hill, east by south; the Seven Hills, east-north-east; Windsor, northeast by east. At a little distance from the spot at which they began the ascent, they found a pyramidical heap of stones [Note 19], the work, evidently, of some European, one side of which the natives had opened, probably in the expectation of finding some treasure deposited in it.
