This is an aerial view from 1960. I have to agree with Stuart that this seems to be the effects of natural erosion at work.

Are these 'humps' not natural features? When water flows down a slope, over time, it erodes it. It doesn't however, erode it in a uniform way, it forms channels. Geologically, Darland Banks form one side of a river valley through chalk bedrock. Chalk is a soft, porous rock and erodes quickly. Given that our climate has been much wetter in the past, could it not have been the case that during the geological past, water has fallen on the banks in such a quantity that it has overwhelmed the natural tendency to soak into the chalk and instead has flowed over it down into the valley, eroding the channels over time. Those channels themselves would in time, weather away and become less pronounced?

I have a postcard of the Darland Banks looking from the Gypsy Camp side and the whole Banks have wavy humps along them?
Do you think the whole area is unstable because of its steepness and type of soil?

Perhaps they are the arched roofs of the legendary Medway tunnel network that links everything to everything else!  ;)

I don't think there are water mains in that area from plans I have seen in the past. There is an 18"gas pipe which aligns from the end of Alison Ave down the banks and follows the line of trees past the Pavilion and out onto Capstone road but the lines do not match that one either.

Darland Banks 'lines'

I posted a picture on the old forum (when I was 'Dinsy') of what I considered to be strange linear features on the Darland Banks, and asked if anyone knew what they were or what had caused them.

A link from a post on this forum to a YouTube video (very sorry, I can't remember in which category I found the link) showed tunnels being dug for water pipes from a reservoir at the top of Darland down to Capstone (presumably to the pumping station), and I wondered if this had anything to do with the features on the banks, although they don't seem to be near the reservoir nor the pumping station!


Unfortunately I no longer have the photo of the lines, but they can be seen from the bottom of Pear Tree Lane/Capstone Road heading towards Ash Tree Lane, with the Waggon at Hale pub on the right. When the sun is low in the sky (and shadows are elongated) they're really quite prominent!

Once we're all allowed out again, I'll get another photo, but until then here is an image from Google Earth. (At least, I hope there is. I have a habit of forgetting to attach the attachments!) The lines are to the left of the compass arrow.

Can anyone shed any light on what they may be?
