It is just a handful of miles SW of Cherry Hill. It is actually for sale at the moment. A "one-way"ish airstrip that has quite a slope upwards in one direction with a large 30' berm immediately at the end of the runway 23 and rising terrain beyond. The other direction (05) is downhill and has falling terrain.
I flew in there for the first time after visiting Cherry Hill and landed, then realized 3 things after landing
1 - That it is at altitude-ish (1730', but this was a hot summer day and density altitude was pushing 4000')
2 - The runway was sloped upwards for runway 23 by 60' over the 2500' length and immediately at the end was a 30' tall dirt berm. Trees are cleared for 2000' so at least that is good.
3 - The winds were strong-ish at 12G20 and in line with the runway, but the wrong way. So a headwind for the uphill 23 or a tailwind for the downhill 05.
4 - Runway 05 ended in a 30' dropoff immediately at the end of the pavement. So an overrun would end up with a long tumble down a hill at the best.
So in my mighty C150 that hates hot days, I had to decide to takeoff uphill into a headwind, or downhill with a strong tailwind. I figured that I had more time to decide to abort going uphill on 23 and did not want to get hit with a big tailwind gust just as I was taking off from 05. I made it over the berm of 23 and had a long low flight over terrain as I climbed above.
But none of this info is alerted strongly enough in the Chart Supplement for 70N, in my opinion. You can see that the runways have a different reported heights, but that is not really info that screams there could be end up being a one-way strip and we probably just gloss over this if not alerted to it. There is an obstruction noted for 05, but it is noted for Runway 05 as a landing obstruction and not a takeoff obstruction for 23, and no mention of the actual runway slope or that you might get screwed if the winds just so happen to be in the exact wrong direction to takeoff downhill. I am sure that no local pilots takeoff uphill and probably just avoid days with the winds like I experienced.
Just a FYI to be careful and a reminder that there are situations that you may miss. If all the cards line up in the wrong way, things can get hairy.
