David was raised on a farm, and has worked in soil
conservation for the 36 years. His job
descriptions have changed from Soil Scientist, to Urban Conservation
Specialist, to Resource Specialist as the agency has evolved from the State
Soil and Water Conservation Committee, IDNR, to the Division of Soil
Conservation, ISDA. David lives in
Bluffton with his wife, Julie. He has 2
grown children and 2 grandchildren.
My wife and I recently took a trip to Alaska and thoroughly enjoyed that great
state. We visited the coastal
rain forests and southeastern Alaska , including
Denali .

There was so much to learn about the geology, history, plant communities
and wildlife, across a variety of environments: Pacific coastal waters, fresh inland bodies of water, mountains, and glaciers.

There are vast areas that are
undeveloped and beautiful. The Fall
color change, especially in Denali
National Park , was a
highlight of our trip.

Unfortunately that beauty is based on thin soil, steep
land, and a cold climate. Consequently,
there was little evidence of agriculture in Alaska .
The economy of Southeast Alaska is
limited to tourism, fishing hunting, and forestry.

Evidence of current and past glaciers were everywhere in Alaska . Alaska
is a theater for viewing glaciers; seeing glacial moraines, braided streams,
and ice disintegration features in their infancy.

These are the same features we see evidenced
in the glaciated soils of Indiana
where glaciers were last seen 10-15,000 years ago.
As pretty as it was, Alaska
made me appreciate the natural resources we have in Indiana .
Coastal Rain Forest-Trees growing from decaying
tree, essentially no soil |
Pasture Stocking Rates for Dall Sheep are quite low (See white specks?) |
We have Prime Farmland and a climate well
suited for agriculture. We have
woodlands and wildlife… but we also grow row crops and raise livestock.
Agriculture is a valuable part of the Indiana Economy.
