GeographyEcho Mountain was shaped from an alluvial fan between Rubio and Las Flores canyons. It is geographically defined by Castle Canyon to its leeward side, Rubio Canyon at its foot, and Las Flores Canyon on its windward side. Echo has a mean elevation of {{Convert|3207|ft|m|0}}. It is most visible as a short mountain extension whose ridge protrudes below the peak of Inspiration Point.{{Citation needed|date=July 2009}} Echo Mountain's name is derived from the number of repetitions one's voice[4] could emit into Castle Canyon. Boy Scout projects were made to find the "sweet spot" where the largest number of repetitions could be heard. During the days of the Mount Lowe Railway "echophones" were set up to assist in voice projections near the best sweet spots.{{Citation needed|date=July 2009}} HistoryOn 6 January 1993, Echo Mountain, also referred to as Mount Echo, was delineated as part of the Mount Lowe Railway monument area listed by the U.S. Forest Service on the National Register of Historic Places. On top of the mountain are the ruins of "White City", a resort along the scenic Mount Lowe Railway, which could easily be seen from the valley below. From its point and down an incline to its foot in Rubio Canyon was the Great Incline funicular of the Mount Lowe Railway, whose white cars could be seen ascending and descending Echo.[5] Trail accessEcho Mountain can be reached by the Sam Merrill Trail located at the top of Lake Avenue, or via the fire road which extends from Millard Canyon to a point along the old right of way, which will lead to the backside of the promontory.[3] References1. ^1 {{cite peakbagger |pid=13473 |name=Echo Mountain, California |accessdate=2009-08-01}} 2. ^{{cite gnis |id=241821 |name=Echo Mountain |accessdate=2009-08-01}} 3. ^1 {{cite summitpost |id=385220 |name=Lower Sam Merrill Trail and Castle Canyon/Middle Sam Merrill Loop |accessdate=2011-05-07}} 4. ^{{cite book | url=https://books.google.com/books?id=9V1IAAAAMAAJ&pg=PA113#v=onepage&q&f=false | title=The Origin of Certain Place Names in the United States | publisher=Govt.
