This post is to show the ramp I dug back at the start of my current Shattered Isles run. I'm not sure it's the most ramp for its purpose, or that focusing on the ramp here is optimal at all, but this forum should have some stuff on it and I like this ramp, so here it is.
I was trying to get up to level 60 of this island (where the copper is) without wasting a ton of time on digging or dumping. I went with a cut-only ramp so that I could use all my fill to access the nearby island with limestone on it.
Since this ramp uses so much natural terrain, it gets from level 3 to level 60 while only using an excavator for the last 1/3 or so of that distance.


Here are the mining designations I used for the ramp

I built it as a temporary solution, but it's still getting plenty of use in year 500.
