What are some examples of juxtaposition in Louise Erdrich's poem "Jacklight"?

Juxtaposition is used often in Louise Erdrich's poem
"Jacklight." One very useful web site defines juxtaposition as
follows:

readability="16">

The arrangement of two or more
ideas, characters, actions, settings, phrases, or words side-by-side or in similar
narrative moments for the purpose of comparison, contrast, rhetorical effect, suspense,
or character development.

Juxtaposition
appears, for instance, in some of the following places in Erdrich's
poem:

• In the juxtaposition of the prose of the
  opening epigraph with the verse of the succeeding
  poem.


• In the sudden shift from active to passive phrasing
  in the transition from line 5 and line 6.


• In the sudden
  shift from plural in the lines 1-7 to singular in lines 8-9.
  


• In the sudden shift back to plural from singular that
  occurs in line 10.


• In the phrase "night sun" (line
  11).


• In the sudden shift from an emphasis on "we" in the
  first three stanzas to an emphasis on "they" in stanza
  four.


• In the shift from the largely attractive imagery of
  the first three stanzas to the largely unattractive imagery of stanza
  four.


• In the abrupt shift that occurs midway through line
  18: "We smell their mothers buried chin-deep in wet dirt." (A similar shift occurs in
  line 21.)


• In the sudden shift back to an emphasis on "we"
  that occurs in line 28.


• In the sudden shift back to
  "they" that occurs in the final
  stanza.
