Agua Negra Pass is a border crossing between Chile and Argentina. At over 4700m it is one of the highest passes between the countries in the world and is only passable outside the winter months.
The road is gravel from the Chile side and brand new asphalt on the Argentina side. (A proposed tunnel has been started from the Argentina side to allow easier access to the Chilean port town of La Serena.
The road from Chile is a gradually climb from the beautiful Elqui Valley region. This should not cause any issue with altitude sickness if you climb at a normal pace. The Argentina side is similar however because the road is asphalt you will be able to climb faster, therefore take your time.
From Chile this road starts at Elqui Valley. From Argentina from the town Las Flores, San Juan Province.

As of 2017, Chile side loose hard packed gravel. Argentina side all paved

Just before you reach the top, on the Chile side, you will experience riding/driving through a glacier. I’m not sure how is cut but the glacier is split to allow the road to pass through it. awesome stuff.
Penitentes are snow formations found at high altitudes. They take the form of elongated, thin blades of hardened snow or ice, closely spaced and pointing towards the general direction of the sun. You can find these amazing formations at the top of the pass. For a stunning drone view of these formations check out this video
