Excavation Point

[Philatone]

hey mark!
just a quick line-by; haven't really read the comments so apologies if I repeat (or none if that makes it more helpful to you!)

biting into the terra firma, ...don't need the article "the" I think
tasting the frozen roots and tubers...or here; nice lines for an opening by the way
with galvanized teeth
this place
is the last place
no other memory makes sense anymore ...at first I wasn't a fan of this line. it really tells a lot if you ask me, and I think there are ways of describing similar feelings. that being said, "memory", in a poem entitled "excavation", is such a powerful word that you could justify this line to me. believe that this line and the previous two would benefit from their own stanza

dumping my favorite in a hole ...I wanted a stronger word than "favorite", and something more specific too
seems so wrong
in this place
the first place
to avoid

...just a thought. if you wanted, I think you could add another stanza here to lead into your close a little more directly

in a few years it will all be over ...another spot where I think you can show rather than tell
requisition a new best
and try to misremember this place ...interesting....
the only place
that she could go

with regards to the punctuation (or "no punctuation")--with some adjusted line spacing, you may be able to get away with it better. I also wanted you to show more than simply tell me what is happening/ what will happen. you really crafted some great wordchoices and lines here (particularly thinking of your opening and "misremember"). sorry if the critique is too heavy for the forum!
