simon3: Track 4216 in area near White Hill, Dublin/Wicklow (Ireland)
Surveying Djouce and its neighbours.
Length: 10.0km, Creator time taken: 4h33m, Ascent: 369m,
Descent: 459m

Places: Start at O16846 07659, White Hill, Djouce, War Hill, end at Start
Logged as completed by 2
On a breezy day a group of MVers set out to measure Djouce. Previous maps had given us no less than three possible heights for the place: OSI 1:50k at 725m, East-West: 733m and the old 6” lists it at 2385 feet = 729.65m (Malin Datum adjusted). Partly this trip was to clarify the height for the upcoming "Irish Peaks" book being produced by Mountaineering Ireland, using MV lists.
While we were at it we decided to measure White Hill and War Hill and the intervening cols.
For both White Hill and War hill the problem is to determine where the top is, both being flattish.
L to r on White Hill: the old top; using the Abney level, reaching the probable highest point.

Previously for White Hill was thought the top was at the outcrop on the left in the picture. But a point some metres distant seemed higher. Our surveyor, member Jackill, whipped out a small Victorian instrument called an "Abney Level" which can determine which of two places is higher. He pronounced a point further on as higher and that was measured using the Trimble professional GPS which can usually measure to around 10cm vertically and horizontally.

After the intervening col we reached Djouce. It is straightforward to see where the top of the natural land is here and our measurement should be within 10cm. The other people present were a group of Scouts that Jackill had brought along for the day.
After measuring Djouce we headed for the col with War Hill, stopping briefly at the "Coffin Stone" well known as a place out of the wind for hillwalkers. What we were looking for was the highest point on the ridge between the two mountains that is also the lowest point on a line between the valleys on either size. We need to find col height to establish the prominence of summits.
The seriously irregular col between Djouce and distant War Hill

In a perfect world of smooth surfaces this would be easy to find, but in reality it is extremely hard and does not remain constant over time given the nature of eroding peat hags.
Measuring what we took to be the current col between War Hill and Djouce.

Accordingly we were aiming to find the height of this point but only to within 1 metre vertical.
Having reached the summit of War Hill we noted that there is a small cairn there however it may not be the highest point. While we were taking measurements of some candidates a lone walker appeared and identified himself as MV member "Prendo".

We returned to the car park by contouring around Djouce and back along the bored-walk. A great days walking and with five positions made a small contribution to accurate measurement of Ireland's mountains.

Conclusions.
  • Djouce height: 725.509m
  • White HillL 631.056m, prominence: 14.37m
  • War Hill: 684.75, prominence: 69.5m
Implications - little change.
  • The height of Djouce rounded to a metre is the same as that on the modern OSI 1:50k map which was published around 1995.
  • The prominence of White Hill is just short of that required for a Vandeleur-Lynam (15m) which is reasonable since it is essentially a rounded southern spur off Djouce. Still, it might have been one.
  • War Hill is 1.25m lower than the OSI figure which does not affect its inclusion in MV lists.
