Could be loess, eolian dunes, or stratified windblown dunes, or sand dunes. The sediments could include sand, clay, silt, or loess.
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
sand dunes and loess
Loess is characterized by being extremely fertile.
Glacially derived loess deposits are typically composed of silt-sized particles, clay, and sand. Sand dunes are composed primarily of sand-sized particles, most often of quartz.

Wind erosion and deposition may form Sand Dunes and Loess Deposits.
Sand dunes are made from mainly one mineral - sand or quartz grains and they form and move to develop a typical cross bedding structure. Loess however is wind blown silt (a mixture of sand and clay) with a fine grain size typically in the 20-50 micrometer range. The deposits are typically non stratified and cover a wide area. They also quickly become loosely cemented after deposition and are not reworked as are sand dunes. The source material for loess deposits is the rock flour left by retreating Ice sheets and the deposits therfore form in temperate regions while Sand Dunes are an indication of arid desert (tropical) conditions.
loess and dunes
There are only two sand dunes in Michigan. The two sand dunes are Sleeping Bear Dunes and Sliver lake sand dunes.
why do you think loess can be carried futher than sand
Maybe the loess deposits are lighter than the sand.
Loess is very fertile while sand is not
Sand dunes are heaps of wind blown sand
the largest sand dunes
sand dunes change
wind blows sand particles to other sand dunes and wa-la your sand dunes grow
No... Silver Lake sand dunes are the largest sand dunes in Michigan.But sleeping bear dunes are the biggest fresh water dunes in the world.
yes sand dunes are big
