Stream or bulk-download raw 3DEP lidar point cloud tiles directly from AWS instead of the USGS download portal, for a large regional terrain model.

Steps
Review the dataset listing at https://registry.opendata.aws/usgs-lidar/ and the GitHub index at github.com/hobuinc/usgs-lidar.
For lossless full-density LAZ tiles, use the Requester Pays bucket s3://usgs-lidar (AWS charges apply for egress/requests).
For a public, no-cost, streamable alternative, use the s3://usgs-lidar-public bucket, which mirrors most (not all) resources as Entwine Point Tiles (EPT) — note some sources with incomplete/missing CRS metadata are excluded from EPT generation.
Browse and visually QA a resource before bulk pulling by using the Potree/Plasio.js viewer index at http://usgs.entwine.io.
For programmatic clipping/streaming rather than whole-tile downloads, use a PDAL or Entwine pipeline pointed at the EPT resource's metadata JSON.
Known gotchas
The public EPT bucket is NOT a complete mirror of the Requester Pays raw LAZ bucket — a project area with CRS-metadata problems in the source data may only be available from the paid bucket.
This AWS distribution is a USGS/Hobu/USACE-CRREL collaboration, not an official USGS API — treat it as a high-performance mirror of 3DEP data, and cross-check point counts/extents against TNMAccess if data provenance needs to be defensible for legal deliverables.
