Yeah, I remember being told the same thing. Probably a bit of a generalization. Probably more true on the lobe and than other parts of Iowa. I think I remember hearing from the same professor if current temperature and precipitation trends continued during this interglacial Iowa would eventually end up being mostly deciduous forest if left undisturbed.

I think we always had that potential as trees and shrubs can grow damn near anywhere. It was the bison and prairie fires that kept trees at bay.

But I agree that if you walked away from everything the way it sits today, within 30-50 years you would see a full covering of deciduous shrub trees that would look like the Cross Timbers area in Oklahoma. Just a tangle of thick underbrush and short trees that choked everything out. A real mess.

he asked if carter lake was the only iowa city west of the missouri river. i said yes, it is.

i then said westfield was the furthest west city in iowa. i never said westfield was west of the missouri river. what exactly are you suggesting?

So is it the only iowa town west of the Missouri river?

Yes. You do realize rivers don't run straight north/south, right?

This is what I was suggesting.

Western Kansas is FLAT and I-80 in Utah across the Bonneville Salt Flats is FLAT. As someone who has driven both those and Western Iowa, Iowa is rolling, not flat.

The stretch between the Missouri and the Loess hills is as flat as flat gets but other than that Western Iowa is definitely not flat. Central Iowa between hwy 30 and hwy 20 can be quite flat as well.

Everytime I go to Omaha I realize how ugly western Iowa is. I'm assuming there's a flood plain there that makes it flat and boring. Certainly compared to eastern Iowa. Area around Marshalltown has a lot more hills than you'd expect, too.

It's weird how mississippi river caused bluffs and missouri river caused floodplain

When you say western Iowa what area are you speaking of geographically? Where I grew up it seemed we were in southwest Iowa and some said we were in western Iowa. According to the Omaha World Herald, sports wise, we were always southwest Iowa.

The Missouri River runs from northwest to southeast, like most rivers in the western half of this country.

Westfield is east of the Missouri River, but it is west of Carter Lake due to the angle the river runs. La Crosse, WI is west of Davenport even though it's on the east side of the Mississippi and Davenport is on the west.


Westfield is actually located adjacent to the Big Sioux River, that dumps in to the Missouri at Sioux City and it's the Missouri the rest of the way.

Salt Flats and Western Kansas it is flat as far as the eye can see, 65 mph and 15 minutes later, flat as far as the eye can, and so on forever it seems

Many years ago coming back from Breckenridge, CO we were coming through Denver, the driver somehow got on I-70 instead of I-76 to get to I-80 around 9 pm. Kinda like the Dumb and Dumber movie, John Denver was still full of Sh#t even as we were going east. Suburban with 6 people in it and the driver had it pegged for about 3 hours. We even turned the lights off as the moon was so bright that night. We were playing follow the leader with another car. I just sat in the back drinking gin and tonics. So we missed Lincoln, NE by and hour or so since we kinda went out of the way. We headed north out of Salina to get to I-80. Trip went pretty fast.

This seems odd down by Keokuk also:

I'm guessing there was a flood and the river re-routed itself, but they kept the boundary line the same. Pretty clear evidence of the old riverbed going where that dashed line is. There are similar areas over by the Omaha airport, too. Starting in Nebraska, you have to drive through Iowa to get to the Omaha airport coming in from the south.

All in on Qwik Star. Far superior to Casey’s and I’m glad they’re expanding heavy into Iowa.

The old franchised Casey's stores were awesome. They all had their own unique things they would make and their pizza and donuts were the best. Now everything is driven by corporate and it just isn't quote the same. I still love Casey's pizza and every once in awhile you will get one that takes ya right back to your childhood.

Not sure if true, but I have heard that Dubuque is the largest city in U.S. without Interstate access.
Is Hwy 20 considered an interstate highway?

Dubuque (at least according to an old radio commercial I grew up with) is Iowa's oldest city on the Mississippi.

Hwy 20 is not in the interstate system. Only routes marked with the R, W & B shield are interstates.

Odd numbers go generally N/S and even numbers generally E/W with routes ending in 5 or 0 generally being border to border or close to it.

Also 3 digit routes starting in an odd number are generally spurs while those starting with an even number generally return to the parent route. e.g. 235 loops off of 35 and back to it while 380 is a spur leaving 80 and not returning.

Finally, lower number N/S routes are west with high number in the east. Lower number E/W routes are in the south with high numbers in the north.

it's all about funding mechanisms and design specs. The interstate numbering system is opposite the US Highway system. Meaning the US Highways start with low numbers in teh east and increase as you go west. To not confuse drivers the Interstates start low in the west and increase as you go east.

Something I never understood was, regarding US Highways, why is US Highway 6 smack dab in the middle of Iowa when all of our other are in sequential order?
6 is considered a diagonal route (at one time it went from Massachusetts to Long Beach California, then the longest federal route in the nation) with its numbering outside of the route numbering norm. 67 is also out of order (east of 61, 63 and 65 in Iowa) but it is an odd duck anyway going from the US Mexican border in W Texas to the Iowa Illinois border. It is more of an E/W route in Texas but a N/S route around the Mississippi River.

It’s definitely a weird stereotype of Iowa. I guess people think fields need to be flat. Another are I’ve spent time in that is FLAT is on I-80 between Sacramento CA and Walnut, CA where you hit the BART station to go in to SF. Specifically around Davis.
I-35 is pretty flat through most of Iowa, especially north of Ames.
