When in Goat MMO, you can hit
for a map of the area. You have to enter areas to "discover" them in MMO fashion, so use the map inside the spoiler for reference if you have not previously visited the mentioned locations in the following guide:
To receive this achievement, you must get a physics impulse from a geyser. There are apparently several, but the one I used was in Glarblargle Beach at the southwestern end of the map. Where the map's marked path takes a sharp western turn, head east of that point to find this geyser.
The geysers never go off when you're standing on them, so you must time your jump to be over the geyser when it goes off. You can make this slightly easier with mutators like double jump or
gravity goat, but there is a small variation in the pause between eruptions so there's always going to be an element of luck involved.
