There were a few ambiguities and places where I had to alter the text slightly.
I put "translation footnotes" at the bottom, marked with asterisks.

To avoid making certain ambiguities and alterations too harmful, I added
"translator's notes"

Winter is like a wolf who captures old people, ill people, and very young
children.
Winter is like a rock; plants cannot grow on this rock
Winter is like sharp claws or merciless teeth*

Therefore we ask you "Will you resemble a playful boy in the spring**?
May you dance*** on the ground. So may the sun, who is your mother, see us. And
may beautiful plants continue to be on your route"

*Literally "merciless bird's mouth" [there is no word for "beak". I struggled
with this, and decided that the spirit of the text would best be served by
"merciless teeth", but added this footnote to, hopefully, allow my successor to
figure out what the original was. :-)]
**Literally "jumping boy of spring" or "boy of the jumping spring"
***Or jump or run in place [run without a goal]

Basic word order is VSO. Subordinate clauses are not marked, but all clauses
must start with a verb, so that if a noun is followed by a verb, it is either a
new sentence or a subordinate clause. Sentences are marked with periods, so
there should be no ambiguity there. Auxilaries are suffixed to their verb.
Verbal agreement is with the argument in the absolutive.

When a verb is in the antipassive, the noun which would normally be absolutive
(i.e., the patient) is marked with instrumental. In this particular text, that
is the only use of the instrumental.

Any action which takes place in the future is marked with nai-, unlike in
English where present tense is often used for future actions. The abscence of a
tense prefix indicates present tense

The aspect suffix -ki requires some explanation. Arguably this has become a
"default aspect". It is used whenever the indicated action is an action which is
going on at the time indicated by the tense. This is almost obligatory with
stative verbs and "to be".

Nouns may take multiple case suffixes. This occurs when one noun modifies
another. The first case indicates the relationship to the head noun, while the
second is agreement, thus _natabif uakibavaf_ (G2-boy-gen G6-forest-loc-gen)
would be "of the boy in the forest".

Adjectives follow nouns, including demonstratives and numbers. Genitives (except
genitive pronouns) come last. Reduplication in adjectives indicates "very" or
"excessively"

Pati- is a difficult prefix. It can mean many things, primarily "group of",
"category characterized by", "belonging to a group" (mostly with nouns like
"spirit" or "goal"), "group of examples of X"
