I was surprised to see Hotondberg (150m)added to the belgian list of mountains. I only live 15 miles from there and know the area very well.
The Hotondberg forms a really flat saddle at the top to the north with Kwaremont (2 miles away) and to the west with Kluisberg (3 miles away)and has only limited prominence to the south east of around 50M towards the city of Ronse and to north east towards city of Oudenaarde. It doesn’t even has a real summit. Honestly I don’t think this mountain should be in the ON SOTA list.
On the other hand the Kemmelberg is higher (159m) and has a real prominence in all directions of around 100m. (G3VQO) might confirm this as he has activated this one and still it has been deleted from the list.
Now I don’t do myself any favours as Kemmelberg is further away (40 miles) from my QTH than Hotond but I believe the latter should be deleted and the former should be reinstated.
