I went for a walk yesterday and explored a park near me that I haven’t been to before. There’s a lot of places near me that I haven’t been to before, because I only recently moved to Royksopp.

It turns out the park contains normal park things (grass, trees, vandalised benches, bins mostly full of water from when it rained). It also contains four mysterious lumps. If I described them to you they’d sound like hills so I am including pictures here to make it clear that they are not hills, they are mysterious lumps, and there are four of them.

They are all different heights and they are perfectly circular, like weird pyramids. You can climb them all if you want to. Three are just grassy and you have to scramble up but one of them has a spiralling path to the top. It’s surprisingly tall – not that West London is particularly hilly, but it’s higher than all the other hills you can see and most of the buildings. You can see out to the countryside south of London, and to Canary Wharf, and to a little thing on the horizon called the Crystal Palace Transmitter which I have seen somewhere before.

The signs explain that, far from being lumps, they are actually mounds. I was very glad to have the mystery cleared up in this way.

Please use this thread to share stories of any intriguing lumps, mounds or protrudances you have witnessed lately.
