Belknap Crater
Eruptions at Little Belknap were "quiet", but voluminous, creating the separate shield, which is topped with cinders and lava blocks with collapsed lava tubes radiating outward. A western tube forms a confluence with a vertical conduit that has a diameter of about . Little Belknap's lava flows extended to within of Windy Point to the east and McKenzie Pass to the southeast, forming deposits over ash from Belknap Crater and covered by lava flows from Yapoah Cone. Along the Skyline Trail, one of the lava flows from Little Belknap peeled back on itself as it cooled, creating overturned slabs of hardened lava with widths up to and lengths up to . The blocks are often parallel to the lava's flow direction; Taylor (1965) called them "lava curls".
