For much of the growing season, we were giving you try-weekly updates on
the maze appearance (meaning we TRY-ed to update the images on a weekly basis).
In addition to those images shown below, we can now offer you
views of the Boiler Mazer through the end of the show on 27 September. The
Web cam is located some 80 feet up in the air on a steel tower erected by
Prairie iNet that is
being used first and foremost for wireless Internet connectivity during the
Farm Progress Show.
Note: The images are arranged in reverse order
with the newest dates listed first. The 'thumbnail' images below are linked to
larger versions. Simply click on the image to 'pop up' a larger one in a new

- The peak of the Boiler Mazer's glory is now behind us. The once lush
green appearance of the corn plants is beginning to change to the golden glow
of harvest maturity. The entrance to the maze is flanked by a lineup of
historical soybean varieties on the left and a collection of crops grown around
the world on the right. The grain is now in the
dent stage of
'milk line', a transition boundary between sugary liquids and drier starch,
is halfway down the kernels. Physiological maturity is 10 to 14 days away.
- 17 Aug 2001
- Since the Maze Cam last visited the Boiler Mazer on 27 July, the crop
has moved along rapidly and is now at the
dough stage of kernel development. The narrower trails are
inviting on a late summer day, but some pesky
and velvetleaf weeds have taken advantage of the wider, more sunlit trails.
- 27 July 2001
- The critical flowering period for the corn in the Boiler Mazer is
nearly complete and all is looking well. The growth stage of the crop is
technically late R1, still silking but almost complete. Kernels will quickly
begin the important
period. The plants are now at their full height, reaching more then ten
feet towards the blue sky. The exposed silks on the ears, having completed
their role in the reproductive process, are beginning to dry out.
- 18 July 2001
- During the past week of warm weather, the plants in the maze have
progressed three leaves to the V17 growth stage (17 leaves with visible leaf
collars). Only about a week remains before the plants enter the critical
Some of the mowed corn in the trails is still trying to recover and stands as a
testament to the survival skills of this King of American Crops! Some
opportunistic weeds, including lambsquarter, are trying to establish a foothold
in the more expansive trail areas of the maze; but their destiny with a hoe

- These aerial images were taken fourteen days after the last flight.
The maze design has become more distinct now that the corn is shoulder- to
head-high (growth stage V12 - 14). The
that spells 'PURDUE' and 'FARM PROGRESS' has become less distinct because of
corn leaves intruding into the narrow widths of those mown areas.
- 10 July 2001
- Since the last corner photo was taken (26 June), the corn has
progressed from the 8-leaf to about the 13-leaf collar stage of development. A
thunderstorm with strong winds passed through the area two days earlier.
Thankfully, little damage occurred in the maze, although there was a minor
proportion of plants that simply snapped in the wind. The phenomenon is termed
'green snap' and occurs most frequently when corn is going
through its rapid growth phase prior to tassel emergence. Plants snap cleanly
in two at a stalk node or joint.

- These aerial images were taken eight days after the initial mowing of
the maze design.
Variability in corn size and height are evident in these
photos. The variability is related primarily to soil type differences in the

- In the seven days since the trails were first mowed, the corn has
progressed two leaf stages and is now at the V8 stage of development. The corn
is about 30 inches tall, not yet tall enough to create claustrophia, but does
begin to create a bit of
for the maze traveler. Since the
points of the plants at the time of mowing were not yet elevated uniformly
above the height of the mower cut, there is
regrowth occurring in the
and especially in the
of the Boilermaker Special.

corn is at the V6 stage of development. Now that the weather has finally warmed
up, the corn is developing at a pace of about one leaf every four days. Here's
closer view of the maze area. Here's an
view of the maze after we finished mowing the design into the standing

- The corn is at the V3 stage of development. The second straight week
of cooler than normal temperatures continues to slow corn development. Here's a
closer view of the maze area.
- 31 May 2001
- The corn is at the V2 stage of development. The slow rate of corn
development since last week is due to the continued unusually cool
temperatures. Here's a
closer view of the maze area.
- 24 May 2001
- The corn is at the V1 stage of development. The intersections and
dead ends of the maze trails are staked and marked with road marking paint. Not
very impressive yet, is it?
