Easy question im not sure about?

Question

on a topographic map the stream flows to where the way the v is pointing or the other way?

Answer 1

apologies

correction: stream SOURCE comes from the top of the V, sorry for my incorrect "upside down" grammar.

I thought I had made a double negative, making my prior statement correct, but rereading realized my grammar had not been correct.

So, yes in my head we were saying the same thing, making it confusing that you called me wrong.

xxTRUE,

The stream flow (downhill) would be oriented in the direction of the bottom of the "V" in a topographic map

Answer 2

webneck: I didn't give you your thumbs-down but you probably got it because your answer is wrong.

On a topographic map the apexes of a series of V's will either represent a ridgeline or a canyon bottom. On a ridgeline, downhill does go in the same direction the V points, but you'll never have a stream along a ridgeline. Streams will be in the bottoms of canyons, where downhill is towards the open end of the V.

Part II:

webneck:

I didn't mean to offend you, and I'm a little confused by your additional statement. You say:

"while it is true that on a ridgeline the "Vs " point uphill, THERE ARE NO STREAMS ON TOP OF A RIDGE."

It's not true that the V's point uphill along a ridgeline, and that's not what I said either. However, "There are no streams on top of a ridge" is pretty much exactly what I said. Perhaps we're both trying to say the same thing? When I think of the way a V points, I'm thinking of starting at the apex of the V and going away from the rest of the V (not going between the two stems towards the open end). Maybe you're thinking of the opposite direction?

Anyway, to illustrate the situation for laughitout123, let's imagine two triangular peninsulas situated next to each-other so that they make a W, where the open ends of the W connect to more land and the two bottom points of the W extend into the water. The shoreline in this case (the W) is also a topographic line because everything along it is at the same elevation (the level of the water). Let's also imagine that the peninsulas are mountainous (not flat), so if we were to draw another contour line at, say, 50 feet elevation - we would get another W above/inside the first W.

In this case each peninsula has a ridgeline, which runs down the center of its side of the W-pair, connecting the two pairs of downward-pointing apexes on each side. We both agree that there won't be any streams here (along the ridgeline). The stream will be in the canyon between the two peninsulas, where there is a pair of apexes pointing up. The stream flows downhill towards the body of water, which is towards the open end of the V formed by the meeting of the two peninsulas.

Thus, on a topographic map, the stream flows in the opposite direction from which the V is pointing.
