Mountain stream: haiku or tanka?

mountain stream talking to myself

pine scent

of a pine
discarded needles

mountaintop hemlocks

the last katydid’s
creaky love song

pitcher plants

the old logging railroad’s
boggy bed

under this lush life

more mountain

cable footbridge

the autumn river’s
unhurried flow

Ogle Township

letting my shadow
lead the way

first fire

all the light that won’t
shine again

old birch

the wild gestures of one
living alone

aviary vulture

the unyielding bones
of its cage

all in black I pass

a walker all in white
autumn mountain

saying hello

to a moss-covered log
heron wingbeats
