Do you have your data in GCS and specified the cellsize of 2. It's a highly inappropriate cellsize for the data. Assuming this is the problem I'd recommend the las file be projected first (e.g., via the ExtractLAS tool - by setting the output SR in the GP environment for the tool.The current LAS SR support does not take the user defined bytes into account when checking the total number of bytes after geo tags. NIM087051 - An LAS file projected using LP360 fails to load into an LAS dataset in ArcGIS 10.1 SP1 with the error, "One or more invalid or unsupported LAS files were ignored."When a LAS dataset is added to ArcScene, the minimum bounding boxes representing the extents of each LAS file in the LAS dataset are shown each time the LAS data is drawn in the scene.

Log ASCII Standard, LAS, is a format specification for storing and distributing digital well log data. The standard was defined and is maintained by the Canadian Well Logging Society (CWLS): http://www.cwls.org/las/. LAS 2.0 is the most used digital well log distribution format. A LAS auxiliary file (.lasx) is created for each LAS file when statistics are calculated on a LAS dataset. The LAS auxiliary files contain the statistical information and spatial index for each LAS file. The new LAS auxiliary file is given the same name as the source LAS file and is stored in the same location on disk.Opening las files. LIDAR Data Exchange File.
