Town Run / Town Run Trail History
« on: August 09, 2012, 08:51:53 AM »
I lifted this all from Paul Arlinghaus' answer to a question about tetanus hill.  This was such a great history lesson I thought I'd save it for posterity 8)

The property was farmed and then quarried for gravel.  In order to protect the quarrying operation a levy was built.  The levy was often built by piling trash (farm fence, old cars, misc equipment, metal trash from the quarrying, etc... and then covering it with dirt.  This was in the late 1800's or early 1900's.

In 1913, there was the largest flood on record in Indianapolis.  The flood was caused in large part by all the flood plains along the White River that had been blocked off by levies.  Many of the levies were broken after the flood to allow the flood plains to do what they are supposed to do (disperse flood waters). 

So the land that is now Town Run Trail Park has been significantly altered from its natural state. 

To fully illustrate the amount of man made changes to the land, look at the next three photos of Town Run South.

Town Run South 1941

Town Run South 1972: Notice the land removed at the oxbow.  This was a gravel operation and the land around the edge was left to act as a levy. 

Town Run South 2010: Only a faint outline of where there used to be land.

The point is that Town Run has a long history.  And some of that history is evident in the metal objects found in the the ground.  There are scattered cables, old farm fence, glass dumps, buried cars, etc.....

So in cases of places like Tetanus Hill, the car buried in the ground is part of Town Run's history. 

Due to the amount of human manipulation and the amount of man made objects buried in the ground, there is no way to remove all such objects. In the case of the car buried in Tetanus Hill, it would take a bull dozer to remove the car, and then there would be no hill left to build a trail.

It also is very dangerous to start removing metal objects that become exposed.  A small piece of metal or wire, could be attached to a bail of farm fence, a car, or large tangled mess of metal.  So in general if metal objects don't have sharp edges or pose the same risk as natural objects like rocks, logs, sticker bushes, etc.... then we leave them alone.

We do look for sharp metal objects along the edge of the trail and try to remove them as we find them.  Keep in mind that these objects tend to work their way to the surface due to natural events like freeze thaw, floods, droughts, etc...  So we will likely never see and end to new objects coming to the surface. 

So in the case of Tetanus Hill, we will not be removing all of the metal parts in the trail tread.  It is a part of the history of Town Run and gives the trail character.  It also would create a more hazardous condition if we started digging out parts of the car, as we would just exposed more of the car.  I will look at the area and remove any sharp objects that pose risks above the normal risks involved in mountain biking

General Trail Information / Spring riding and Trail Status reminder...
« on: March 26, 2012, 06:53:42 AM »
Hi Folks,

I know we have a lot of new members on our friendly forum, so I wanted to post a reminder about spring riding, how we set the Trail Status, and what the different colors mean.

In early spring, the cooler night and morning temperatures bring the moisture to the trail's surface, making them fairly snotty in the mornings. If you can hold off until afternoon, you'll most likely find hero dirt. That said, it's hard to set the HMBA Trail Status for the exact conditions at any given moment. For that reason, we've outlined the guidelines below for each of the colors:

GREEN = Friggin awesome.. Go Ride!

YELLOW = Wet and possibly sloppy in spots. If you're leaving ruts, or feel you're doing damage, please bail on your ride.

RED = Wet, do not ride. We don't turn a trail red lightly, and do not ride means please.. do not ride. If you want to go check out the trail on foot and report back on improved conditions, please feel free.

BLUE = Freeze/Thaw. This status is saved for winter, and you won't see it much in the spring. It means it might be hard frozen in the morning and good for a ride, but thawing out by afternoon.

Okay, that's about it. If you have any questions, please feel free to post here.


HMBA Website Suggestions, Comments, etc. / Karma Camelion....

Hi Gang,
I've been hearing some grumblings that some folks don't like the Karma function on our friendly HMBA Forum. We instituted this when we upgraded the forum template last year, just as a fun tool. Some, however, are afraid it's sending the wrong message to folks. So, let's take a vote. I'll be running this poll for the next 30 days. Do you like the Karma function, or should we dump it?
Let your voice be heard! Oh, and don't worry. The votes are anonymous, so you won't be smote. 8)

General Trail Information / Freeze Thaw Cycles and Trail Status
« on: November 18, 2011, 06:56:49 AM »
Hi Folks,

It's that time of year again, where the mornings are cold and frozen and the afternoons can be sunny and warm.. well, warmish. This makes for great late fall riding, but can be hard on the trails, due the the freeze thaw cycles. When the trails freeze overnight, ice crystals form in the soil. The day's warming melts these crystals, and can cause the trail to become slick as snot on a winter's day. For this reason, we'll probably just leave the Trail Status yellow on days like these. Mostly because the trails will be slick in the morning, and probably fantastic by afternoon. There's no way us mere humans with jobs can keep changing the trail status with the changing conditions. So, if the trail is Yellow, it's still okay to ride. Just know you might encounter slick areas in the morning. If the freeze thaw cycles are bad enough that it will cause damage, we'll turn the trail Red. Until then.. have fun, and be careful!

Re-posted from another topic so we can keep it locked and easily accessible. Since this trail system is still under construction, we'll be updating this as things progress

Jeff Blum put this map together:
Fort Ben

Thanks to everyone who are working so hard on this fantastic city trail!

Have biking friends who don't know about the Hoosier Mountain Bike Association facebook page? Did you even know we have one? Check us out, tell your friends, send invites, help us keep the public informed about trail conditions, work sessions at your favorite trail, and special events. Let's see if we can get the "likes" over 2000!


I'd like to send out a big thanks to all of you who post your trail observations on our individual Trail Conditions forums. Those of us who monitor and update the Trail Status system try to be as accurate as possible, and we can't do it without your input.

Thanks, and keep up the great work!!

It's almost that time of year again folks. With cold nights and sunny days, we have to start keeping in mind the impact such weather has on our trails. Please read below. Thanks!

When soil freezes all the moisture turns to ice crystals between the particles of the soil  and in clay or loam soil they are tightly packed together. As the moisture freezes the crystals expand and tear the clay apart shattering it, then as it thaws the soil become more porous and allows more moisture in. This is repeated with every successive thaw.

In Indiana we can get as many as 100 freeze thaw cycles in a season.

So, please be very careful when trying to ride the trails in the winter. The best time to ride is when the trail is frozen solid.  On days when the temperature goes below freezing at night, the worst thing we can do is wait for the sun to come out and warm up the trail before riding.  The trails can be very soft even if it hasnít rained recently. Even if the temperature stays below freezing South facing trails can defrost in sunlight and turn to mush.

If you are leaving ruts in the trail where you have ridden please leave the trail. The ruts will allow even more water to remain on the trail and make it even worse. If people see you riding they will want to ride too, so very soon the trail reaches a point of meltdown.


Please keep an eye on the Trail Status lights at the top of the forum, and on www.hmba.org.  We will do our best to keep this information accurate during this winter's freeze thaw cycles. Thanks!

HMBA Forum News and Information / www.hmba.org Trail Status Chart
« on: March 31, 2010, 12:45:10 PM »
Check out www.hmba.org for our new Trail Status chart. Right now, it covers Town Run, Brown County, Versailles, O'Bannon, Westwood, Rangeline, and Southwestway. We'll be working on expanding this to other trails as we re-organize our forums under some new classifications (more to follow on that subject). Here's the key to the chart:

Red = Wet - Stay off the trail
Yellow = Fair - Some sloppy spots are present, use caution
Green = Dry - GET OUT AND RIDE!!!!!!!!!!!!!!!!!!!

We're also working to make this script more compatible with our CMS (content management system) in order to add "hover over" text, and possibly hot links to the forum.

So post those forum trail condition updates coming (or send me a PM), I'll be using these to update the status.
