Talk:Pistyll Rhaeadr

Untitled
The height of the waterfall cannot be both 240 foot and 75 metres. 240 foot is 73.152 metres. Even with significant rounding errors, it should never be 75 metres. The sign by the waterfall quotes it as 240 foot. The BBC page (see the external links) calls it "240 ft (74 metres)" which must also be wrong, since 74 metres is closer to 243 feet. So ... what is the actual height of the waterfall?

Aside from that, the "waterfall" is actually 3 waterfalls. The large upper part, the middle part under the natural arch, and the lower part into the plunge pool. What does the height refer to; the total height? Or the unbroken upper height? As far as I can tell (by using humans for scale in photographs) it is the total height, which would be cheating when trying to claim it as a record height for wales. The highest part would be around 40 metres. Aber Falls are about 36.5 metres - allowing for rounding errors, they could possibly be taller than the tallest waterfall at Pistyll.

The sign by the waterfall says "The height from the lip at the top to the pool at the bottom measures 240 feet.". Could this all be somehow clarified in the article, once someone establishes what the correct heights are? —Preceding unsigned comment added by 82.13.95.125 (talk) 09:29, 14 May 2008 (UTC)

More details:

So far, every page I can find says that the height is 240 feet. Various places say this is 73, 74, or 75 metres, of which 73 is the closest to 240 feet.

This government leaflet is probably the best source: http://www.tourism.powys.gov.uk/brochures/Powys-Walks-Booklet.pdf

Since this says it is 73 metres, I will update the height on the wikipedia page, and make references as needed. —Preceding unsigned comment added by 82.13.95.125 (talk) 13:28, 20 May 2008 (UTC)

This waterfall cannot be the highest
"Rock Climbing in Snowdonia" (http://www.amazon.com/gp/product/0711224080) ISBN-10: 0711224080 ISBN-13: 978-0711224087. Lists the "Devil's Appendix" waterfall in Cwm Idwal as 93 metres tall (used for ice climbing when it freezes). The book can be previewed here: http://books.google.com/books?id=wn3yNgWGttoC&pg=PA107&lpg=PA107&dq=%22devil's+appendix%22+waterfall&source=bl&ots=dxBbLkagd3&sig=hjolGt0HwacPG7rm_lx48Pb75nk&hl=en&ei=8febStGlNsaZjAfJ3pzmDQ&sa=X&oi=book_result&ct=result&resnum=1#v=onepage&q=%22devil's%20appendix%22%20waterfall&f=false

My own photos confirm this height, and show that the waterfall is an almost unbroken fall - it certainly deserves to be ranked higher than Pistyll Rhaeadr. However, its flow is usually quite low, so it is not always obvious; this is probably why it is not normally mentioned as the tallest. TarquinWJ (talk) 17:26, 31 August 2009 (UTC)

To the person who added back incorrect information stating that the waterfall is the highest, there is a compiled list of heights here: http://www.cavinguk.co.uk/holidays/waterfalls/Tallest.html Pistyll rhaeadr does not make it to the top of the list either in single drop height or in total height.
