This note was posted to the Titanium Bolting FB Group 10th March 2020 Warning: This gets a bit geekey, but I’ll simplify as much as possible. For the past few years I have concentrated on providing sufficient evidence for the theory that all marine crags showing SCC of 304SS are associated with high sulphate levels. […]
This note was posted to the Titanium Bolting FB Group 7 March 2020 Everyone knows and loves those huge lower-off rings we find at the top of climbs at Railay/Tonsai.However, some of us began to love them a whole lot less when it became clear that they too were subject to the dreaded SCC. If […]
This note was posted to the Titanium Bolting FB Group 29 January 2020 The hero of this piece is Martin Roberts who burnt countless hours of quality time, when he could have been climbing, installing a large range of anchor types in a whole pile of locations across Railay/Tonsai. My motto is to “measure more and […]
This note was posted to the Titanium Bolting FB Group 27 January 2020 I promise this is the last “distance from the sea” post ….. for a little while at any rate I say extra, because here I’m talking about Heuco Wall (just 50m beyond Low Tide Wall), and this is one of a number […]
This note was posted to the Titanium Bolting FB Group 21 January 2020 Bit of a back story here…. When I first visited Railay, some 12 years ago, I had heard stories about perfectly good-looking SS bolts snapping under body-weight, but being ever the scientific skeptic, I thought I’ll believe that when I see it […]
This note was posted to the Titanium Bolting FB Group 16 January 2020 Today I measured spot sulphates at three points on the set of cliffs containing Diamond Cave, ending with a sample from Diamond Cave North climbing area itself. All showed zero levels as I would expect for a crag 300m from the sea. […]
This note was posted to the Titanium Bolting FB Group 16 January 2020 A consistent feature of the “sulphur crag” story, especially at Railay/Tonsai is that sulphate is not found any distance more than 100m or so from the sea. Thus it is no surprise that the white deposit found at Wee’s Present Wall shown […]
This note was posted to the Titanium Bolting FB Group 14 January 2020 The large cave at the Pra Nang side of Klao Luk Choee is home to the classic Todd Skinner route Best Route in Minnesota. At the base of that route there is a white powdery material in great abundance. Analysis shows it […]
This note was posted to the Titanium Bolting FB Group 12 January 2020 The “sulphur” crag story continues. Here we see calcium sulphate crystals deposited on the surface of the rock at Defile Exit, Railay. I hypothesise that this material is deposited as a result of bio/geochemical processes occurring at the rock surface due to […]
