Unique capability of LEND to measure epithermal neutron albedo with high spatial resolution allow to create maps with resolution up to 10 km of this type of neutrons albedo for circumpolar areas. Analysis of these maps for both poles shows existence of areas with relatively strong suppression of epithermal neutron flux (named as Neutron Suppressed Regions or NSRs), which are interpreted as areas with high concentration of hydrogen in regolith. The most unique property of NSRs is that their boundaries may located outside of or may not correlate at all with a positions of Permanently Shadowed Regions (PSRs). Currently available neutron data from LEND allowed to identify several local areas around both lunar poles, which might have rather high content of water ice about several weight percents within ~ 1 meter layer of sub-surface.
