3D models are ideal for showing the basic simplicity of corner hollows. 3D shows very clearly the hollow with obvious corner rim grooving. The real power of these is that each example shows exactly the same phenomenon being repeated. Even more important is the fact that several of these examples are indisputable ‘Evidence Boulders’. (See page on Evidence split boulders).
8 Examples of Corner Hollows with Rim Grooving:
PB48, PB56 and PB51 are split Evidence Boulders
PB61 and PB62 are close together
PB32a is in Cavan Burren carpark.
Carrickcreevagh is in Glenfarne
Cavan Burren PB48 Corner hollow
Cavan Burren PB56 Corner hollow
Cavan Burren PB51 Corner hollow – this is part of a split boulder, the corner on one section worked contrasting with unworked corresponding corner. It is an ‘Evidence Boulder’
Cavan Burren PB 71 high
Cavan Burren PB61 Corner hollow
Cavan Burren PB62
Pb32a Corner hollow
8 Examples of Corner Hollows with Channels
In addition to corner hollows, with rim grooving, the following examples also have channels. Several of these examples are on ‘Evidence Boulders’.
704 has two channels and corner hollows plus Notch and Peak and these are validated by split ‘Evidence’ Boulder’
PB84 has converging channels
PB86 has a deep corner hollow with a channel sloping downward into hollow.
PB105 has a deep corner hollow with a channel
PB71 has a corner hollow with a channel
704 has a channel and Notch and Peak. These are validated by split ‘Evidence’ Boulder’
PB53 has a narrow deep channel
Cavan Burren 704 Channels and peak
Cavan Burren PB84 Corner Hollows and converging Channels
- Cavan Burren PB105 deep Corner Hollow and Channel
- Cavan Burren PB71 Corner Hollow and Channel
- Cavan Burren PB40 channel + peak
- Cavan Burren PB53 Channel
Examples of Notches and Peaks :
PB46 & PB48 show very obvious, and almost identical, Notches & Peaks. PB48 is also an ‘Evidence Boulder’ which validates these as types.
704 & PB40 also have almost identical Notches & Peaks and both are ‘Evidence Boulders’. (See 3D models above)
H14 and PB85 both display prominent Peaks, PB85 is an ‘Evidence Boulder’.
Cavan Burren PB46 Channels + Peak
PB48 Corner Channels + Peak
Cavan Burren H14 Peak Corner
Cavan Burren PB85 channel
